The video data 42, audio data 43 as audio information, and sub-picture data 44 as sub-picture information. Here, only video data is recorded as the video data 42, and only audio data is recorded as the audio data 43. Further, as the sub-picture data 44, only graphic data such as characters and figures as a sub-picture is recorded. The standard stipulates that up to eight types of audio can be recorded on the DVD-R1R and up to 32 types of sub-video can be recorded.

  The playback time corresponding to one VOB unit 30 (playback time corresponding to data recorded between one navigation pack 41 and the navigation pack 41 adjacent to the one navigation pack 41) is 0. It is recorded so as to have a length of 4 seconds or more and 1 second or less. Therefore, the navigation pack 41 is always detected once every 0.4 second to 1 second during reproduction.

  Further, in one VOB unit 30, the navigation pack 41 is always present at the head thereof, but the video data 42, the audio data 43, and the sub-picture data 44 are not necessarily present in the VOB unit 30, and Even if they exist, their number and order can be arbitrarily set.

  Here, each of the video data 42, audio data 43, and sub-picture data 44 shown in FIG.

  That is, in one VOB unit 30, video data 42, audio data 43, and sub-picture data 44 are divided and recorded in packs P, and the pack P in which the video data 42 is recorded is recorded as video. The pack P in which the audio data 43 is recorded is called an audio pack, and the pack P in which the sub-picture data 44 is recorded is called a sub-picture pack. Further, in the pack header recorded at the head of each pack P, the data contained in each pack P is read from the track buffer in the information recording / reproducing apparatus for reproducing the information recorded on the DVD-R1R. Read start time information called SCR (System Clock Reference) indicating the read start time on the reproduction time axis at which input to each buffer is to be started is recorded. For each pack P, video data 42, audio data 43 or sub-picture data 44 is normally recorded for each packet which is a recording unit obtained by further subdividing the pack P. In -R1R, one pack P is generally composed of one packet.

  Finally, the navigation pack 41 searches information for searching for video or audio to be reproduced and displayed (specifically, an address on the DVD-R1R in which the video or audio to be reproduced and recorded is recorded). ) DSI data 51, and PCI data 50 that is information related to playback display control when displaying video or audio searched based on DSI data 51. At this time, the DSI data 51 and the PCI data 50 are recorded as a DSI packet and a PCI packet as the packet PT, respectively.

  Further, all the video data 42 included in one VOB unit 30 is composed of one or a plurality of GOPs (Group Of Pictures).

  The DSI data 51 and the PCI data 50 will be described in detail later.

  Further, the PCI data 50 includes highlight information defining the display and operation when the item is selected for the selection item selected by the viewer. With this highlight information, for example, in the image (the so-called menu screen) displaying the item to be selected by the viewer, the screen display change with respect to the item selection, the display position to be changed corresponding to the selection, and the selected Settings such as a command for an item (an instruction indicating an operation to be performed on a selected item) are performed.

  Here, the image information for displaying the frame, the selection button, and the like necessary for configuring and displaying the menu screen is recorded as the sub-picture data 44 that is the sub-picture information.

  Furthermore, the above GOP is played back independently as defined in the MPEG (Moving Picture Expert Group) 2 standard, which is an image compression system employed when recording video information on the DVD-R1R in this embodiment. Reproduction display time information called PTS (Presentation Time Stamp) indicating the reproduction time on the reproduction time axis on which the video data 42 included in the GOP is to be displayed is the smallest possible image unit. To be recorded.

  Here, the outline of the MPEG2 system will be described. In general, in continuous frame images, frame images before and after one frame image are often similar to each other and have a mutual relationship. The MPEG2 system pays attention to this point, and based on a plurality of frame images transferred several frames apart, another frame image existing between the plurality of frame images is interpolated based on the motion vector of the original image. It is a method to generate by. In this case, when recording the other frame image, it is only necessary to record the information about the difference and motion vector between the plurality of frame images. Thus, the other frame image can be reproduced. As a result, compressed recording of images becomes possible.

  Furthermore, the outline of the GOP will be described with reference to FIG. FIG. 3 shows an example of a plurality of frame images constituting one GOP. FIG. 3 shows a case where one GOP 52 is composed of 12 frame images (the number of frame images included in one GOP 52 is not constant in the MPEG2 system). The frame image indicated by “I” is called an I picture (Intra-coded picture) and refers to a frame image that can reproduce a complete frame image only with its own image. Also, the frame image indicated by the code “P” is called a P picture (Predictive-coded picture) and has been compensated and reproduced based on an already decoded I picture or another P picture. This is a predicted image generated by decoding a difference from the predicted image. The frame image indicated by the code “B” is called a B picture (Bidirectionally predictive-coded picture), and is recorded on an optical disc or the like as well as an already decoded I picture or P picture. A predicted image that is reproduced by using a future I picture or P picture for prediction. Here, in FIG. 3, the prediction relationship (interpolation relationship) between the pictures is indicated by arrows.

  Note that in the general MPEG2 system used in DVDs including the DVD-R1R according to the embodiment, a variable rate system in which the amount of data included in each GOP 52 is not constant is adopted. That is, when each picture included in one GOP 52 corresponds to a fast moving video and the correlation between the pictures is small, the amount of data for configuring each picture increases. The amount of data included in the GOP 52 also increases. On the other hand, when each picture included in one GOP 52 corresponds to a moving image that does not move much and the correlation between the pictures is large, the amount of data for configuring each picture is also reduced. The amount of data included in the GOP 52 is also reduced.

  In the above-described physical format having the hierarchical structure shown in FIG. 2, each category is recorded by the producer of the record information by freely setting the category according to the intention. By performing reproduction for each of these sections based on the logical structure described later, various reproductions with various changes can be made.

  Next, a detailed configuration of the video manager 2 will be described with reference to FIG.

  First, the video manager 2 is a VMGI (Video Manager Information) 4 as the main body of the video manager 2 which is information related to the entire video information and audio information recorded on the DVD-R 1 R, and other accompanying information. And other information 5.

  Next, the VMGI 4 includes an access table 6 for accessing each title described above, a menu indicating the name of each title, information for preventing illegal copying, backup information of these information, and the like as other information. And other information 7.

Second type information 9 and other information 12 that is other information are included. At this time, the second type information 9 is recorded together with the recording information on the DVD-R1R as will be described later (in this respect, the first type information 145 that has been recorded in advance in the manufacturing stage). This is 2-bit information, and in the case of DVD-R1R, the value is “10b”.

  Further, the other information 12 includes version information indicating the version number of the physical format standard currently described.

  Note that the second type information 9 and second type information 88 described later are also used in other DVDs such as a read-only DVD, the recordable DVD-RW, and the DVD-RAM. As with the one-type information 145, the value is “00b” for a read-only DVD, “01b” for a DVD-RAM, and “11b” for a DVD-RW. Respectively.

  Next, the physical data structures of the DSI data 51 and the PCI data 50 will be described with reference to FIG.

  First, as shown in FIG. 5, the PCI data 50 includes general information 55 as the main body of the PCI data 50 and other information 56 that is other information.

  Further, the general information 55 includes the navigation pack relative position information 70 that is relative recording address information from the top of the VOB 10 of the navigation pack 41 and the playback time axis of the VOB unit 30 in which the navigation pack 41 is included. VOBU playback start time information 71 indicating the playback start time in VOBU, VOBU playback end time information 72 indicating the playback end time on the playback time axis of the VOB unit 30, and other information 73 as other information. ing.

  Next, the DSI data 51 is reproduced before and after the general information 75 as the DSI data 51 main body, the VOB information 76 that is information on the VOB 10 to which the navigation pack 41 belongs, and the VOB unit 30 to which the navigation pack 41 belongs. VOBU search information 77 indicating a recording position on the DVD-R1R of another VOB unit 30 to be performed, and other information 78 which is other information.

  The general information 75 includes navigation pack relative position information 85 similar to the navigation pack relative position information 70, a VOBU identification number 86 for identifying the VOB unit 30 to which the navigation pack 41 belongs, and other information. And other information 87 and 2-bit second type information 88 having the same value as that of the second type information 9.

  Further, the VOB information 76 includes VOB playback start time information 80 indicating the playback start time on the playback time axis of the VOB 10 to which the VOB unit 30 including the navigation pack 41 belongs, and a playback end time on the playback time axis of the VOB 10. VOB playback end time information 81 and other information 82 that is other information.

  Furthermore, as the VOBU search information 77, the next VOB unit 30 of the VOB unit 30 to which the navigation pack 41 belongs, the position information indicating the recording position on the DVD-R1R of the previous VOB unit 30, and the VOB. Position information indicating the recording positions on the DVD-R1R of other VOB units 30 to be reproduced in the range from 120 seconds to 120 seconds before the start time of the unit 30 is included as a list as shown in FIG. Yes.

  Of the above-described information, information for managing the reproduction mode of recorded information, such as the video manager 2, the control data 11, the navigation pack 41, and the PTS in each pack header, is collectively referred to as navigation information.

  Next, a logical format (logical structure) in which recording information recorded by the physical divisions shown in FIGS. 2, 4 and 5 is combined will be described with reference to FIG. Note that the logical structure shown in FIG. 6 does not actually record information on the DVD-R1R in that structure, but the logical structure shown in FIG. In particular, information (access information, time information, etc.) for reproducing by combining the cells 20) is recorded on the DVD-R 1R, particularly in the control data 11.

  For clarification of the description, starting from the lower hierarchy of FIG. 6, one program 60 is produced by selecting and combining a plurality of cells 20 in the physical format described in FIG. Logically based on the intent of the person. This program 60 is also the smallest logical unit that can be accessed by a command by the system controller in the information reproducing apparatus identifying the partition. The producer can also define the program 60 as a minimum unit in which one or a plurality of programs 60 can be freely selected and viewed, and this unit is referred to as a PTT (Part of Title).

  In addition, since one program 60 is logically configured by selecting a plurality of cells 20, one cell 20 is used in a plurality of programs 60, that is, one cell 20 is used in a plurality of different programs 60. It is also possible for the producer to reuse the so-called cell 20 to be reproduced.

  Here, the number of one cell 20 is treated as a cell ID number when the cell 20 is handled in the physical format shown in FIG. 2 (shown as cell ID # in FIG. 2), and is shown in FIG. When handled in the logical format, the cell numbers are handled in the order of description in PGCI described later.

  Next, by combining a plurality of programs 60, one PGC (Program Chain) 61 is logically configured based on the intention of the producer. The above-described PGCI is defined in units of the PGC 61, and in the PGCI, the reproduction order of the cells 20 for each program 60 when the respective programs 60 are reproduced (the program unique to each program 60 by this reproduction order). A number is assigned), an address that is a recording position of each cell 20 on the DVD-R1R, a number of the first cell 20 to be reproduced in one program 60, a reproduction method of each program 60 (DVD- of this embodiment) When recording information in R1R, during playback, normal playback, random playback (random playback by random numbers, the same program 60 may be played multiple times) or shuffle playback (similar to random playback) Random playback using random numbers, but the same program 60 is played back only once. Any one of the playback methods can be selected and played back for each PGC 61.) and various commands (for each PGC 61 or each cell 20). Command that can be specified by the user).

  Note that the recording position of the PGCI on the DVD-R1R is in the control data 11 (see FIG. 2) as described above, but when the PGCI is a PGCI related to a menu in the video manager 2, the recording of the PGCI is performed. The position is in control data (not shown) included in the video manager 2.

  In addition to the PGCI, one PGC 61 includes data such as substantial video and audio as a combination of programs 60 (in other words, as a combination of cells 20).

  Further, in one PGC 61, it is possible to reuse the cell 20 shown in the description of the program 60 (that is, the same cell 20 is used by different PGCs 61). In addition to the method of reproducing the cells 20 in the order stored in the DVD-R1R (reproduction of continuously arranged cells), the cells 20 to be used are reproduced regardless of the order stored in the DVD-R1R. The producer can select a method (for example, reproduction of cells 20 recorded later) (reproduction of non-continuous arrangement cells).

  Next, one title 62 is logically configured by one or a plurality of PGCs 61. The title 62 is a unit corresponding to, for example, one movie, and is complete information that the producer wants to provide to the DVD-R1R viewer.

  One or more titles 62 logically constitute one VTS 63. The titles 62 included in the VTS 63 have common attributes. For example, a movie in a different language corresponds to each title 62 for one same movie. Also, information corresponding to one VTS 63 shown in FIG. 6 corresponds to information included in one VTS 3 shown in FIG. That is, on the DVD-R1R, all information logically included in the VTS 63 shown in FIG. 6 is recorded as one VTS3.

  Based on the logical format described above, the producer specifies the recording information divided in the above-described physical format, thereby forming a title (movie or the like) to be viewed by the viewer.

(III) Embodiment of Information Recording / Reproducing Apparatus Next, the recorded information is recorded on a DVD-R1R or DVD-RW (hereinafter simply referred to as DVD-R1R) according to the physical format described above, and the recorded information is recorded. An information recording / reproducing apparatus according to an embodiment for reproducing information from a DVD-R1R or the like will be described with reference to FIGS.

  7 is a block diagram showing a schematic configuration of the information recording / reproducing apparatus according to the embodiment, FIG. 8 is a flowchart showing the information recording process according to the embodiment, and FIG. 9 executes the reproduction process of the recorded information. FIG. 10 is a flowchart showing a so-called loading process (that is, a loading process for loading a DVD-R1R or the like into the information recording / reproducing apparatus of the embodiment) executed in the process, and FIG. 10 is a flowchart showing the information reproducing process according to the embodiment.

  As shown in FIG. 7, the information recording / reproducing apparatus S according to the embodiment includes a recording unit, a pickup 120 as a first detection unit and a second detection unit, a modulation unit 121, a formatter 122, a video encoder 123, Audio encoder 124, system controller 125 as type information recording means and reproducing means, memory 127, demodulator 128, video decoder 129, audio decoder 130, servo IC (Integrated Circuit) 131, and spindle motor 132 And an operation unit 133, a multiplexer 134, and a demultiplexer 135. Further, the system controller 125 includes a navigation information generator 126 that generates the above-described navigation pack 41 and the like.

  Next, the outline operation of each part will be described.

  First, the spindle motor 132 rotates the loaded DVD-R 1 R and the like at a preset rotation speed based on the spindle control signal Sss from the servo IC 131.

  On the other hand, video information Sv as recording information to be recorded in the data area DA such as DVD-R1R is input from the outside and then input to the video encoder 123.

  Based on the control signal Scv from the system controller 125, the video encoder 123 performs a predetermined encoding process on the video information Sv (specifically, for example, the above-described MPEG2 compression encoding process), An encoded video signal Sev is generated and output to the multiplexer 134.

  On the other hand, audio information Sa as recording information to be recorded in the data area DA such as DVD-R1R is input from the outside and then input to the audio encoder 124.

  Based on the control signal Sca from the system controller 125, the audio encoder 124 performs a preset encoding process on the audio information Sa (specifically, for example, the above-mentioned MPEG2 compression encoding process), An encoded audio signal Sea is generated and output to the multiplexer 134.

  As a result, the multiplexer 134 superimposes (multiplexes) the image information and audio information included in the encoded video signal Sev by a preset process, generates a superimposed signal Smx, and outputs it to the formatter 122. .

  At this time, the multiplexer 134 passes the encoded audio signal Sea as it is to obtain the superimposed signal Smx.

  Next, the formatter 122 generates a navigation information signal Snd from a navigation information generator 126 (to be described later) and the superimposed signal Smx based on a control signal Scf from the system controller 125 as shown in FIG. 2, FIG. 4, and FIG. The signals are combined so as to have the format, and a format signal Smt is generated and output to the modulation unit 121.

  At this time, each recording information input to the formatter 122 as the superimposed signal Smx is used as the recording information signal Sfm at a preset timing so as to be used for generation of the navigation information in the navigation information generator 126. Is output.

  Then, the modulation unit 121 performs a predetermined modulation process (specifically, for example, a so-called 8-16 modulation process) on the format signal Smt, generates a modulation signal Sfe, and outputs the modulation signal Sfe to the pickup 120.

  As a result, the pickup 120 generates the light beam B whose intensity is modulated by the modulation signal Sfe, and irradiates the information track in an information recording surface (not shown) such as a DVD-R1R to include the light beam B in the modulation signal Sfe. Pits corresponding to the navigation information and each recorded information are formed on the information track, and the navigation information and each recorded information are recorded on the DVD-R1R or the like in the physical format shown in FIGS. To do.

  At this time, the deviation in the direction perpendicular to the information recording surface and the horizontal direction between the condensing position of the light beam B and the information track is based on the pickup servo signal Ssp output from the servo IC 131. An objective lens (an objective lens for condensing the light beam B) (not shown) is moved in the vertical direction and the horizontal direction (that is, so-called focus servo control and tracking servo control are executed). The

  Therefore, the servo IC 131 generates the spindle control signal Sss and the pickup servo signal Ssp based on the control signal Ssc from the system controller 125, and outputs them to the spindle motor 132 and the pickup 120, respectively.

  On the other hand, when reproducing recorded information or the like already recorded on a DVD-R1R or the like, the pickup 120 generates a reproduction light beam B having a constant intensity and irradiates the information track on which the pits are formed. Then, based on the reflected light, a detection signal Spp corresponding to the recording information or the like is generated and output to the demodulator 128.

  Thus, the demodulator 128 performs a demodulation process corresponding to the modulation process in the modulator 121 on the detection signal Spp, generates a demodulated signal Spd, and outputs the demodulated signal Spd to the demultiplexer de135.

  When the demodulated signal Spd includes video information, the demultiplexer 135 separates image information and audio information included in the video information, generates a separated signal Sdmx, and outputs the separated signal Sdmx to the video decoder 129.

  On the other hand, when the demodulated signal Spd includes only audio information, the demultiplexer 135 passes the demodulated signal Spd as it is and outputs it to the audio decoder 130.

  Next, based on the control signal Scdv from the system controller 125, the video decoder 126 performs a decoding process corresponding to the encoding process at the fixed encoding rate in the video encoder 123 on the separated signal Sdmx, and the decoded video signal Sdv. Is output to an external monitor (not shown).

  Further, the audio decoder 130 performs a decoding process corresponding to the encoding process of the fixed encoding rate in the audio encoder 124 on the demodulated signal Spd including the audio information based on the control signal Scda from the system controller 125, An audio signal Sda is generated and output to an external amplifier (not shown) or the like.

  Further, the operation unit 133 generates an operation signal Sin corresponding to the operation and outputs the operation signal Sin to the system controller 125 when an operation for executing a recording process or a reproduction process in the information recording / reproducing apparatus S is performed by the user. To do.

  Further, the navigation information generator 126 includes the navigation information including the navigation information to be recorded on a DVD-R1R or the like during a recording process to be described later based on the control of the system controller 125 based on the operation signal Sin and the recording information signal Sfm. A signal Snd is generated and output to one input terminal of the formatter 122.

  As a result, the formatter 122 superimposes the recording information in the superimposed signal Smx and the navigation information in the navigation information signal Snd, and the format signal Smt including the recording information having the physical format shown in FIGS. Will be generated.

  In parallel with these operations, the system controller 125 exchanges necessary information as the memory signal Sm with the memory 127, and controls each of the control signals Scv, Sca, Scf, Ssc for controlling the operations. , Scdv and Scda are generated and output to the corresponding components, respectively, and the recording process and the reproduction process described below are comprehensively controlled.

(I) Embodiment of Recording Process Next, the recording process of recording information according to the embodiment will be specifically described with reference to FIG. Note that the recording process described below is a regular (non-illegal) recording that is executed by loading a DVD-R1R or the like (except for a DVD-RAM) that is a DVD that can be recorded on the information recording / reproducing apparatus S. It is processing.

  As shown in FIG. 8, in the recording process of the embodiment, when the DVD-R1R or the like is loaded and an instruction to start the recording process is executed in the operation unit 133, first, the loaded DVD-R The first type information 145 already recorded in R1R or the like is detected (step S1).

  Next, the content of the detected first type information 145 is confirmed (step S2), and when the value is “0010b” indicating that it is a DVD-R1R (step S2; YES), the second type information is displayed. 9 (second type information included in VMGI4) and 88 (second type information included in DSI data 51) are set as “10b” in navigation information generator 126 (step S3). Recording is started (step S4). As a result of the processing in step S4, recording information including the first type information 145 and the second type information 9 and 88 is recorded in the loaded DVD-R 1R in the physical format shown in FIGS. Go.

  Then, it is confirmed whether or not an operation for stopping the recording process has been performed in the operation unit 133 (step S5). If not (step S5; NO), the process returns to step S4 to continue the recording process. On the other hand, when the stop operation is performed (step S5; YES), the recording process is stopped at that time (step S6), and the series of recording processes is ended.

  On the other hand, if the content of the detected first type information 145 is not “0010b” in the determination in step S2 (step S2; NO), then the detected content of the first type information 145 is DVD-RW. It is confirmed whether or not “0011b” is present (step S7).

  When the detected value of the first type information 145 is “0011b” (step S7; YES), the second type information 9 and 88 are set as “11b” in the navigation information generator 126, respectively. (Step S8) Recording of recording information is started (Step S4) and the processing after Step S5 is executed. Here, in the process of step S4 this time, the recording information is recorded in the loaded DVD-RW in the physical format shown in FIGS.

  In the illegal recording process described above, the processes in steps S3 and S8 in FIG. 8 are not executed. As a result, in the optical disc on which the illegal recording process has been performed, the first type information 145 is stored. The contents and the contents of the second type information 9 and 88 are different, or the second type information 9 and 88 are not recorded at all. More specifically, for example, when the recorded information recorded on the reproduction-only DVD is illegally copied to the DVD-R1R by the bit-by-bit method, the second type information 9 and 88 is the reproduction-only DVD. That is, it remains “00b”.

  In the determination of step S7, if the content of the first type information 145 is not “0011b” (step S7; NO), the content of the first type information 145 is not “0010b” or “0011b” after all. Therefore, in this case, since the currently loaded DVD is a reproduction-only DVD whose first type information is “0000b”, the recording process is immediately stopped.

(Ii) Embodiment of Reproduction Process Next, the reproduction process according to the embodiment for reproducing the recording information in the DVD-R1R or the like in which the recording information is recorded by the recording process shown in FIG. This will be described with reference to FIG.

(A) Embodiment of Loading Process First, a process when a DVD-R1R or the like is loaded into the information recording / reproducing apparatus S at the time of reproducing recorded information will be described with reference to FIG.

  As shown in FIG. 9, in the loading process of the embodiment, first, a DVD-R1R or the like is inserted from a loading port (not shown) in the information recording / reproducing apparatus S, and the spindle motor 132 is rotated by a loading mechanism (not shown). The loading process for fixing to the shaft is started (step S10).

  Then, it is confirmed whether or not the loading of the DVD-R1R or the like is completed (step S11). If it is not completed (step S11; NO), the process returns to step S10 again to continue the loading process. If it is (step S11; YES), then the rotation of the DVD-R1R and the like and the condensing of the light beam B are started via each servo control described above (step S12).

  Then, the start information and the like (including the first type information 145) in the lead-in area LIA and the VMGI4 are read (step S13).

  Thereafter, in step S13, it is confirmed whether or not VMGI4 has been normally read (step S14). When the VMGI4 has not been read normally (step S14; NO), the recording information recorded on the DVD-R1R has been described above. After notifying the user that the physical format is not compliant, the process proceeds to the next playback process.

  On the other hand, when the VMGI 4 is normally read (step S14; YES), next, initial confirmation such as confirmation of the version number of the physical format is performed based on the read VMGI 4 (step S15). Then, the content of the first type information 145 that has been read (step S13) is confirmed, and it is confirmed whether or not the value is “0000b” indicating that it is a reproduction-only DVD (step S16). ).

  When the content of the first type information 145 is “0000b” (step S16; YES), it is next determined whether or not the second type information 9 in the VMGI 4 is “00b” ( Step S17).

  As a result, when the second type information 9 is “00b” (step S17; YES), the process proceeds to the next reproduction process on the assumption that a regular reproduction-only DVD is loaded in the information recording / reproducing apparatus S. .

  On the other hand, if it is determined in step S17 that the second type information 9 is not “00b” (step S17; NO), the type and second type information of the optical disc indicated by the first type information 145 in the currently loaded optical disc. 9 is different from the type of the optical disk, and it is highly likely that this optical disk is an optical disk formed by illegally copying recorded information. Ejecting (step S22), the reproduction process including the loading process is terminated.

  On the other hand, if it is determined in step S16 that the detected content of the first type information 145 is not “0000b” (step S16; NO), then “0010b” indicating that the value is DVD-R1R. It is confirmed whether or not there is (step S18).

  When the content of the first type information 145 is “0010b” (step S18; YES), it is next determined whether or not the second type information 9 is “10b” (step S19). .

  Thereby, when the second type information 9 is “10b” (step S19; YES), it is assumed that the current regular DVD-R1R is loaded in the information recording / reproducing apparatus S, and the process proceeds to the next reproduction process.

  On the other hand, if it is determined in step S19 that the second type information 9 is not “10b” (step S19; NO), the optical disc type and the second type information indicated by the first type information 145 in the currently loaded optical disc. 9 is different from the type of the optical disk, and it is highly likely that this optical disk is an optical disk formed by illegally copying recorded information. Ejecting (step S22), the reproduction process including the loading process is terminated.

  Further, when the content of the detected first type information 145 is not “0010b” in the determination in step S18 (step S18; NO), next, “0011b” indicating that the value is DVD-RW. It is confirmed whether or not (step S20).

  When the content of the first type information 145 is “0011b” (step S20; YES), it is next determined whether or not the second type information 9 is “11b” (step S21). .

  As a result, when the second type information 9 is “11b” (step S21; YES), it is assumed that a regular DVD-RW is currently loaded in the information recording / reproducing apparatus S, and the process proceeds to the next reproduction process.

  On the other hand, if it is determined in step S21 that the second type information 9 is not “11b” (step S21; NO), the optical disc type and the second type information indicated by the first type information 145 in the currently loaded optical disc. 9 is different from the type of the optical disk, and it is highly likely that this optical disk is an optical disk formed by illegally copying recorded information. Ejecting (step S22), the reproduction process including the loading process is terminated.

(B) Embodiment of Reproduction Process Next, a reproduction process according to an embodiment executed following the above-described loading process will be described with reference to FIG.

  As shown in FIG. 10, in the reproduction process of the embodiment, first, the start information and the like and the VMGI 4 are read from the optical disc currently loaded in the information recording / reproducing apparatus S, and the read VMGI 4 is read. Based on this, initial confirmation such as confirmation of the version number of the physical format is executed (step S25).

  When the initial confirmation is completed, next, the content of the first type information 145 that has been read (step S25) is confirmed, and whether the value is “0000b” indicating that it is a reproduction-only DVD. It is confirmed whether or not (step S26).

  When the content of the first type information 145 is “0000b” (step S26; YES), reproduction of the recorded information recorded in the first type information 145 (detection from the optical disk) is started (step S27). Further, it is determined whether or not the second type information 88 in the DSI data 51 is “00b” (step S28).

  As a result, when the second type information 88 is “00b” (step S28; YES), the reproduction process is continued, assuming that the current reproduction-only DVD is loaded in the information recording / reproducing apparatus S, and the next In addition, it is confirmed whether or not an operation for stopping the reproduction process has been executed in the operation unit 133 (step S29).

  When the stop operation is not executed (step S29; NO), the process returns to step S27 to continue the reproduction process, and the value of the second type information 88 in each DSI data 51 sequentially obtained as the reproduction is continued. On the other hand, when the stop operation is executed (step S29; YES), the reproduction process is stopped as it is (step S30), and the series of reproduction processes is ended.

  On the other hand, if it is determined in step S28 that the second type information 88 is not "00b" (step S28; NO), the type and second type information of the optical disc indicated by the first type information 145 in the currently loaded optical disc. Since the type of the optical disk indicated by reference numeral 88 is different and it is highly likely that this optical disk is an optical disk formed by illegally copying recorded information, the reproduction process for the optical disk is immediately stopped (step At the same time, the optical disk is ejected from the information recording / reproducing apparatus S (step S32), and the reproduction process is terminated.

  Furthermore, when the content of the detected first type information 145 is not “0000b” in the determination of step S26 (step S26; NO), next, “0010b” indicating that the value is DVD-R1R. It is confirmed whether or not there is (step S33).

  When the content of the first type information 145 is “0010b” (step S33; YES), reproduction of the recorded information recorded in the first type information 145 (detection from the optical disk) is started (step S34). Further, it is determined whether or not the second type information 88 is “10b” (step S35).

  As a result, when the second type information 88 is “10b” (step S35; YES), the reproduction process is continued, assuming that the regular DVD-R1R is currently loaded in the information recording / reproducing apparatus S, and then Then, it is confirmed whether or not an operation for stopping the reproduction process has been executed in the operation unit 133 (step S36).

  When the stop operation is not executed (step S36; NO), the process returns to step S34 to continue the reproduction process, and the value of the second type information 88 in each DSI data 51 sequentially obtained as the reproduction is continued. On the other hand, when the stop operation is executed (step S36; YES), the reproduction process is stopped as it is (step S30), and the series of reproduction processes is terminated.

  On the other hand, if it is determined in step S35 that the second type information 88 is not “10b” (step S28; NO), the type and second type information of the optical disc indicated by the first type information 145 in the currently loaded optical disc. Since the type of the optical disk indicated by reference numeral 88 is different and it is highly likely that this optical disk is an optical disk formed by illegally copying recorded information, the reproduction process for the optical disk is immediately stopped (step At the same time, the optical disk is ejected from the information recording / reproducing apparatus S (step S32), and the reproduction process is terminated.

  On the other hand, if it is determined in step S33 that the content of the detected first type information 145 is not “0010b” (step S33; NO), next, “0011b” indicating that the value is DVD-RW. It is confirmed whether or not there is (step S37).

  When the content of the first type information 145 is “0011b” (step S37; YES), reproduction of the recorded information recorded in the first type information (detection from the optical disk) is started (step S38). Further, it is determined whether or not the second type information 88 is “11b” (step S39).

  Thereby, when the second type information 88 is “11b” (step S39; YES), the reproduction process is continued, assuming that the regular DVD-RW is currently loaded in the information recording / reproducing apparatus S, and then Then, it is confirmed whether or not an operation for stopping the reproduction process has been executed in the operation unit 133 (step S40).

  When the stop operation is not executed (step S40; NO), the process returns to step S38 to continue the reproduction process, and the value of the second type information 88 in each DSI data 51 sequentially obtained as the reproduction is continued. On the other hand, when the stop operation is executed (step S40; YES), the reproduction process is stopped as it is (step S30), and the series of reproduction processes is terminated.

  On the other hand, if it is determined in step S39 that the second type information 88 is not “11b” (step S39; NO), the optical disc type and the second type information indicated by the first type information 145 in the currently loaded optical disc. Since the type of the optical disk indicated by reference numeral 88 is different and it is highly likely that this optical disk is an optical disk formed by illegally copying recorded information, the reproduction process for the optical disk is immediately stopped (step At the same time, the optical disk is ejected from the information recording / reproducing apparatus S (step S32), and the reproduction process is terminated.

  Finally, if it is determined in step S37 that the content of the detected first type information 145 is not “0011b” (step S37; NO), the currently loaded optical disc can be reproduced by the information recording / reproducing apparatus S. Assuming that there is no type of optical disk (for example, DVD-RAM), the reproduction process for the optical disk is immediately stopped (step S31), and the optical disk is ejected outside the information recording / reproducing apparatus S (step S32). To do.

  As described above, according to the recording process and the reproducing process in the information recording / reproducing process of the embodiment, the second type information 9 and 88 having the same contents as the first type information 145 recorded in advance are stored in the first type information. After recording on the DVD-R1R or the like in which the type information 145 is recorded, the recording information is recorded on the DVD-R1R or the like, and the first type information 145 and the second type information 9 or 88 are recorded when the recorded information is reproduced. Is reproduced only when they are in the same relationship, the illegal recording process in which the second type information 9 or 88 different from the first type information 145 is recorded or the second type information 9 or 88 is not recorded is illegal. The reproduction of the recorded information recorded by the recording process can be prohibited.

  Further, since the second type information 9 is recorded in the VMGI 4 and the second type information 88 is further recorded in the DSI data 51, even if one of the second type information 9 or 88 is falsified, the other type information 9 is recorded. By using the two types of information 88 or 9, it is possible to reliably prohibit the reproduction of the recorded information recorded by the illegal recording process.

(IV) Modified Embodiment of Information Recording / Reproducing Device Next, a modified embodiment of the information recording / reproducing device according to the present invention will be described with reference to FIGS.

  In the information recording / reproducing apparatus S of the above-described embodiment, the case where the second type information 9 and 88 have different values for each detailed disc type has been described. A value for discriminating the types of two optical disks called DVDs, for example, the value of the second type information 9 or 88 corresponding to a reproduction-only DVD is set to “00b”, and a recordable DVD (ie, DVD-R, DVD-RW) Alternatively, the value of the second type information 9 or 88 corresponding to any one of the DVD-RAM may be set to “01b”.

  In this case, the value of the first type information 145 is “0000b” indicating that the DVD is a reproduction-only DVD, and the value of the second type information 9 or 88 is “0lb” indicating that the DVD is recordable. At that time, the optical disk is configured to be configured so that reproduction of the optical disk is stopped and ejected to the outside, assuming that there is a high possibility that the recorded information is illegally copied from a read-only DVD to a recordable DVD. It becomes.

  On the other hand, when the value of the first type information 145 is “0000b” indicating that the DVD is a reproduction-only DVD, and the value of the second type information 9 or 88 is “00b” indicating that the DVD is a reproduction-only DVD. Or “0001b”, “0010b” or “0011b” indicating that the value of the first type information 145 is a recordable DVD, and the value of the second type information 9 or 88 can also be recorded. In the case of “01b” indicating that the DVD is a new DVD, the recording information recorded on the optical disc is reproduced as it is not illegal.

  Next, the operation of the information recording / reproducing apparatus according to the above-described modification will be described in more detail. Note that the configuration of the information recording / reproducing apparatus according to the modified embodiment is exactly the same as that of the information recording / reproducing apparatus S of the above-described embodiment, and will not be described below.

  First, the operation of the information recording / reproducing apparatus according to the modification described below will be described using a DVD-R having a configuration different from that of the DVD-R1R to which the information recording / reproducing apparatus S of the above-described embodiment is applied. First, a DVD-R having the different configuration will be described with reference to FIG. FIG. 11 is a diagram showing a plan view of a DVD-R according to a modified embodiment and a physical recording format in which recording of recording information is completed.

  As shown in FIG. 11, the DVD-R1R ′ according to the modified embodiment includes a non-recording area 110, a beam intensity test area 111, a management data area 112, a lead-in area LIA, a file similar to the DVD-R1R in the above-described embodiment. A system information area FS, a data area DA, a lead-out area LOA, and a termination area EA are provided, and a plurality of pieces of sector information ST as information units are recorded in the data area DA. It is comprised by.

  One sector information ST is used to correct an identification information ID for identifying the sector information ST itself in the recording information from the head address and a detection error of the identification information ID when reproducing the recording information. Error correction information IED, characteristic information CP indicating characteristics of information included in the sector information ST, main information MD that is information itself included in the sector information ST, and reproduction of recorded information And error detection information EDC for detecting a detection error of the entire sector information ST.

  At this time, regarding the configuration of the characteristic information CP, when the DVD-R1R ′ is a DVD-R1R ′ that should be generally distributed (hereinafter, the DVD-R1R ′ is simply referred to as a G (General) type DVD-R). As shown in FIG. 11A, the characteristic information CP is video information in which the recording information recorded on the G-type DVD-R is mainly composed of image information because of its address configuration. The type information ADP indicating the above has a configuration sandwiched between two preliminary information R that does not include any significant information (hereinafter, the configuration of the characteristic information CP illustrated in FIG. Called).

  On the other hand, the DVD-R1R ′ is a DVD-R1R ′ (hereinafter referred to simply as an A (Authoring) type DVD) that should be used only by a producer of recorded information for testing in the manufacture of a reproduction-only DVD. -R), the characteristic information CP is recorded at the head of copyright information (that is, recorded on the A-type DVD-R) due to its address structure, as shown in FIG. Copyright information indicating the number of times that the recorded information can be copied, reproduction restriction status, etc.) CCI is included, and the characteristic information CP other than the copyright information CCI is reserved information R that does not contain any significant information. (Hereinafter, the configuration of the characteristic information CP shown in FIG. 11B is referred to as a first format).

  Regarding the above-described characteristic information CP, the configuration of the characteristic information CP in the recording information recorded on the DVD-RW and DVD-RAM is the second format in addition to the G-type DVD-R. On the other hand, in addition to the A-type DVD-R, the configuration of the characteristic information CP in the recording information recorded on the reproduction-only DVD is the first format. Specifically, the content of the type information ADP is “01b” when the recording information recorded on the DVD on which the type information ADP is recorded is video information, while the recorded information is When it is not video information (for example, data for an electronic computer), it is set to “00b”.

  Next, the operation of the modified information recording / reproducing apparatus will be described using the DVD-R1R ′ having the above-described configuration.

(I) Modified Embodiment of Recording Process First, a recording information recording process in an information recording / reproducing apparatus according to a modified embodiment will be specifically described with reference to FIG. The recording process described below is executed by loading a recordable DVD (any recordable DVD including the DVD-R1R ′ and DVD-RAM) on the information recording / reproducing apparatus according to the modified embodiment. Is a regular (not illegal) recording process.

  FIG. 12 is a flowchart showing the recording process. The same operation as the recording process in the information recording / reproducing apparatus S according to the embodiment described in FIG. Omitted.

  As shown in FIG. 12, in the recording process of the modified embodiment, when the DVD-R1R ′ or the like is loaded and an instruction to start the recording process is executed in the operation unit 133, first, as in the case of the embodiment. Similarly, the first type information 145 already recorded on the loaded DVD-R1R ′ or the like is detected (step S1).

  Next, the content of the detected first type information 145 is confirmed (step S50), and the value is “0011b” indicating that the loaded DVD is a DVD-RW, or the DVD-RAM is used. When it is “0001b” indicating that it exists (step S50; YES), the second type information 9 (second type information included in the VMGI 4) and 88 (second type information included in the DSI data 51) are displayed. Each is set as “01b” in the navigation information generator 126 (step S54), and the content of the characteristic information CP is set as the second format and the type information ADP is set as “01b” in the navigation information generator 126. (Step S55) Recording of recording information is started in the same manner as in the embodiment (step S4).

  On the other hand, if the content of the first type information 145 is neither “0011b” nor “0001b” in the determination in step S50 (step S50; NO), then the content of the first type information 145 is loaded. It is confirmed whether or not the current DVD is “0010b” indicating that it is DVD-R1R ′ (step S2). If the content is “0010b” (step S2; YES), it is then confirmed whether or not the DVD-R1R ′ is the A-type DVD-R (step S51). When it is not -R (step S51), the process proceeds to steps S54 and S55.

  On the other hand, if it is determined in step S51 that the loaded DVD-R1R ′ is an A-type DVD-R (step S51; YES), the second type information 9 and 88 are set to “00b”, respectively, as a navigation information generator. In step S52, the content of the characteristic information CP is set in the navigation information generator 126 as the first format (step S53), and recording of the record information is started (step S4).

  In step S52 of FIG. 12, “00b”, which is a value originally indicating a reproduction-only DVD, is set in spite of the A-type DVD-R being loaded in the information recording / reproducing apparatus in the modified form. The value of the second type information 9 and 88 is used only for testing when the A-type DVD-R is not distributed to general consumers but is used for manufacturing a read-only DVD. This is because the test needs to function only as a reproduction-only DVD.

  Then, it is confirmed whether or not an operation for stopping the recording process has been performed in the operation unit 133 (step S5). If not (step S5; NO), the process returns to step S4 to continue the recording process. On the other hand, when the stop operation is performed (step S5; YES), the recording process is stopped at that time (step S6), and the series of recording processes is ended.

  On the other hand, if it is determined in step S2 that the detected content of the first type information 145 is not “0010b” (step S2; NO), the content of the first type information 145 is eventually “0001b”, “0010b”, or “0011b”. In this case, since the currently loaded DVD is a reproduction-only DVD (that is, a DVD whose first type information 145 is “0000b”), recording is immediately performed. Stop processing.

  In the above-described illegal recording process, the processes in steps S52 and S54 in FIG. 12 are not executed. As a result, in the optical disk on which the illegal recording process has been performed, the case of the above embodiment is used. Similarly, the content of the first type information 145 is different from the content of the second type information 9 and 88, or the second type information 9 and 88 are not recorded at all.

(Ii) Embodiment of Reproduction Process Next, the reproduction process according to a modified embodiment for reproducing the recorded information in the DVD-R1R ′ etc. in which the recorded information is recorded by the recording process shown in FIG. And it demonstrates using FIG.

(A) Modified form of loading process First, a process when a DVD-R1R 'or the like is loaded into an information recording / reproducing apparatus of a modified form during reproduction of recorded information will be described with reference to FIG.

  FIG. 13 is a flowchart showing the loading process, and the same operations as those in the loading process in the information recording / reproducing apparatus S according to the embodiment described with reference to FIG. Omitted.

  As shown in FIG. 13, in the loading process according to the modified embodiment, first, the content confirmation process (step S10) of the loading process according to the embodiment described in FIG. Up to step S16) is executed.

  Next, if it is determined in step S16 that the content of the first type information 145 is “0000b” (step S16; YES), the currently loaded DVD is a reproduction-only DVD. Then, the characteristic information CP is extracted from the sector information ST in the recording information recorded on the reproduction-only DVD, and it is confirmed whether or not the content of the type information ADP included in the characteristic information CP is “01b”. (Step S60).

  If the content of the confirmed type information ADP is “01b” (step S60; YES), the type information ADP is not originally defined in the read-only DVD and the A-type DVD-R (FIG. 11). Since the content of the first type information 145 confirmed in step S16 is “0000b” and the type information ADP is “01b”, in this case, some illegal processing is performed. If there is a possibility that the optical disk is currently loaded, the optical disk is immediately ejected out of the information recording / reproducing apparatus (step S22), and the reproducing process including the loading process is terminated.

  On the other hand, if it is determined in step S60 that the content of the confirmed type information ADP is not “01b” (step S60; NO), it is assumed that a regular reproduction-only DVD is currently loaded, and then VMGI4 It is determined whether or not the second type information 9 therein is “00b” (step S17).

  As a result, when the second type information 9 is “00b” (step S17; YES), it is determined that a regular reproduction-only DVD is currently loaded in the information recording / reproducing apparatus S, and the loading process is terminated. Shift to the playback process.

  On the other hand, if it is determined in step S17 that the second type information 9 is not “00b” (step S17; NO), the type and second type information of the optical disc indicated by the first type information 145 in the currently loaded optical disc. 9 is different from the type of the optical disk, and it is highly likely that this optical disk is an optical disk formed by illegally copying recorded information, so that the optical disk is immediately ejected out of the information recording / reproducing apparatus. (Step S22), and the reproduction process including the loading process is terminated.

  On the other hand, if it is determined in step S16 that the content of the detected first type information 145 is not “0000b” (step S16; NO), next, “0011b” indicating that the value is DVD-RW. It is confirmed whether or not it is “0001b” indicating that it is a DVD-RAM (step S61).

  If the content of the first type information 145 is not “0001b” or “0011b” in the determination in step S61 (step S61; NO), then “0010b” indicating that the value is DVD-R1R ′. Is checked (step S62).

  If the content of the first type information 145 is “0010b” (step S62; YES), it is next checked whether the currently loaded DVD-R1R ′ is a G-type DVD-R. (Step S63).

  If the content of the first type information 145 is not “0010b” (step S62; NO), the currently loaded DVD is a DVD that does not belong to any of the regular types. Immediately ejects the optical disk out of the information recording / reproducing apparatus (step S22), and terminates the reproducing process including the loading process.

  Next, if it is determined in step S63 that the currently loaded DVD-R1R ′ is not a G-type DVD-R (step S63; NO), whether or not the DVD-R1R ′ is an A-type DVD-R. Is confirmed (step S64).

  When the loaded DVD-R1R ′ is not an A-type DVD-R (step S64; NO), according to the first type information 145, the currently loaded DVD is DVD-R1R ′. Although it is determined that it is neither G-type DVD-R nor A-type DVD-R, in this case, the optical disc may be an optical disc formed by illegally copying recorded information. Assuming that the optical disc is high, the optical disc is immediately ejected from the information recording / reproducing apparatus (step S22), and the reproducing process including the loading process is terminated.

  On the other hand, if it is determined in step S64 that the currently loaded DVD is an A-type DVD-R (step S64; YES), the recorded information recorded on the A-type DVD-R is then recorded. It is confirmed whether or not encryption processing has been performed (step S65). If it is encrypted (step S65; YES), the recorded information is protected by copyright law, and the DVD-R1R ′ is immediately ejected out of the information recording / reproducing apparatus on the assumption that it should not be reproduced. (Step S22) The reproduction process including the loading process is ended. On the other hand, when it is not encrypted (Step S65; NO), it is recorded on the loaded A-type DVD-R. The characteristic information CP is extracted from the sector information ST in the recording information, and it is confirmed whether or not the content of the type information ADP included therein is “01b” (step S66).

  When the content of the confirmed type information ADP is “01b” (step S66; YES), as described above, the type information ADP is not defined in the read-only DVD and the A-type DVD-R. (Refer to FIG. 11) Since the content confirmed in step S64 is an A-type DVD-R and the type information ADP is “01b”, in this case, some sort of illegal processing has been performed. Assuming that there is a possibility that the DVD-R is currently loaded, the optical disk is immediately ejected out of the information recording / reproducing apparatus (step S22), and the reproducing process including the loading process is terminated.

  On the other hand, if it is determined in step S66 that the content of the confirmed type information ADP is not “01b” (step S66; NO), it is assumed that a regular A-type DVD-R is currently loaded. It is determined whether or not the second type information 9 in the VMGI 4 is “00b” (step S17).

  As a result, when the second type information 9 is “00b” (step S17; YES), it is assumed that a regular A-type DVD-R is currently loaded in the information recording / reproducing apparatus, and the process proceeds to the next reproduction process. .

  On the other hand, if it is determined in step S17 that the second type information 9 is not “00b” (step S17; NO), the DVD type and the second type information indicated by the first type information 145 in the currently loaded optical disc. Since the type of the optical disk indicated by 9 is different, it is highly probable that this DVD is an optical disk formed by illegally copying recorded information, and the optical disk is immediately removed from the information recording / reproducing apparatus. Ejecting (step S22), the reproduction process including the loading process is terminated.

  It should be noted that in step S17 shown in FIG. 13, although it is the A-type DVD-R that is currently loaded in the information recording / reproducing apparatus in the modified form and is the target of the determination, FIG. The A-type DVD-R is not distributed to general consumers as described above, but is used for testing when manufacturing a reproduction-only DVD. This is because it is necessary to function only as a reproduction-only DVD for the test.

  On the other hand, in the determination in step S61, the content of the first type information 145 is either “0001b” or “0011b” (step S61; YES), or the currently loaded DVD in the determination in step S63. -When it is confirmed that R1R 'is a G-type DVD-R (step S63; YES), next, whether or not the encryption processing is performed on the recorded information recorded on each DVD. Is confirmed (step S67). If it is encrypted (step S67; YES), the recorded information is protected by the copyright law, and the optical disc is immediately ejected out of the information recording / reproducing apparatus as it should not be reproduced ( Step S22) The reproduction process including the loading process is finished. On the other hand, when the reproduction process is not encrypted (Step S67; NO), the sector information ST in the recording information recorded on the loaded DVD is next. The characteristic information CP is extracted from the information, and it is confirmed whether or not the content of the type information ADP included in the characteristic information CP is “01b” (step S68).

  If the content of the confirmed type information ADP is not “01b” (step S68; NO), as described above, the type information ADP records video information on the DVD-RW, DVD-RAM, or G-type DVD-R. In this case, the contents confirmed in step S61 or S63 and the contents confirmed in step S68 do not match. In this case, the optical disc on which some illegal processing has been performed. Is immediately loaded out of the information recording / reproducing apparatus (step S22), and the reproducing process including the loading process is terminated.

  On the other hand, when the content of the confirmed type information ADP is “01b” (step S68; YES), the content confirmed in step S61 or S63 is appropriate as a regular DVD-RW, DVD-RAM, or DVD-R. Then, it is determined whether or not the second type information 9 is “01b” (step S69).

  As a result, when the second type information 9 is “01b” (step S69; YES), the G-type DVD-R, DVD-RW, or DVD-RAM that is currently capable of reproducing the recorded information normally can be used. As one of them is loaded in the information recording / reproducing apparatus, the process proceeds to the next reproducing process.

  On the other hand, if it is determined in step S69 that the second type information 9 is not “01b” (step S69; NO), the optical disc type and the second type information indicated by the first type information 145 in the currently loaded optical disc. 9 is different from the type of the optical disk, and it is highly likely that this optical disk is a DVD formed by illegally copying recorded information, so that the optical disk is immediately ejected out of the information recording / reproducing apparatus. (Step S22), and the reproduction process including the loading process is terminated.

(B) Modified Embodiment of Reproducing Process Finally, a reproducing process according to a modified embodiment executed subsequent to the above-described loading process will be described with reference to FIG.

  FIG. 14 is a flowchart showing the reproduction process. The same operation as the reproduction process in the information recording / reproducing apparatus S according to the embodiment described with reference to FIG. Omitted.

  As shown in FIG. 14, in the reproduction process of the modified embodiment, first, the initial confirmation process (step S25) to the reproduction start process (step S27) of the reproduction process according to the embodiment described in FIG. 10 are executed. Is done.

  When reproduction is started, next, the characteristic information CP is extracted from the sector information ST in the recording information recorded on the reproduction-only DVD confirmed in step S26, and the type included in the characteristic information CP is extracted. It is confirmed whether or not the content of the information ADP is “01b” (step S75).

  When the content of the confirmed type information ADP is “01b” (step S75; YES), as described above, the type information ADP is not defined in the read-only DVD and the A-type DVD-R. (Refer to FIG. 11) It is impossible that the content of the first type information 145 confirmed in step S26 is “0000b” and the type information ADP is “01b”. Assuming that there is a possibility that the processed optical disk is currently loaded, the reproducing process for the optical disk is immediately stopped (step S31), and the optical disk is ejected from the information recording / reproducing apparatus (step S32), and the reproducing process is ended. To do.

  On the other hand, if it is determined in step S75 that the content of the confirmed type information ADP is not “01b” (step S75; NO), it is assumed that a regular reproduction-only DVD is currently loaded, and then the DSI It is determined whether or not the second type information 88 in the data 51 is “00b” (step S28).

  As a result, when the second type information 88 is “00b” (step S28; YES), the reproduction process is continued, assuming that a regular reproduction-only DVD is currently loaded in the information recording / reproducing apparatus. Then, it is confirmed whether or not an operation for stopping the reproduction process has been executed in the operation unit 133 (step S29).

  When the stop operation is not executed (step S29; NO), the process returns to step S27 to continue the reproduction process, and the value of the second type information 88 in each DSI data 51 sequentially obtained as the reproduction is continued. On the other hand, when the stop operation is executed (step S29; YES), the reproduction process is stopped as it is (step S30), and the series of reproduction processes is ended.

  On the other hand, if it is determined in step S28 that the second type information 88 is not "00b" (step S28; NO), the type and second type information of the optical disc indicated by the first type information 145 in the currently loaded optical disc. Since the type of the optical disk indicated by reference numeral 88 is different and it is highly likely that this DVD is an optical disk formed by illegally copying recorded information, the reproduction process for the optical disk is immediately stopped (step At the same time, the optical disk is ejected from the information recording / reproducing apparatus (step S32), and the reproducing process is terminated.

  On the other hand, if it is determined in step S26 that the detected content of the first type information 145 is not “0000b” (step S26; NO), next, “0011b” indicating that the value is DVD-RW. Whether or not it is “0001b” indicating that it is a DVD-RAM is confirmed (step S76).

  If the content of the first type information 145 is not “0001b” or “0011b” in the determination in step S76 (step S76; NO), then “0010b” indicating that the value is DVD-R1R ′. "Is confirmed (step S77).

  When the content of the first type information 145 is “0010b” (step S77; YES), it is next checked whether the currently loaded DVD-R1R ′ is a G-type DVD-R. (Step S78).

  If the content of the first type information 145 is not “0010b” (step S77; NO), the currently loaded DVD is a DVD that does not belong to any of the regular types. Immediately determines that the optical disk is an unknown optical disk (step S31) and ejects the optical disk to the outside of the information recording / reproducing apparatus (step S32), and ends the reproduction process.

  Next, if it is determined in step S78 that the currently loaded DVD-R1R ′ is not a G-type DVD-R (step S78; NO), whether or not the DVD-R1R ′ is an A-type DVD-R. Is confirmed (step S79).

  When the loaded DVD-R1R ′ is not an A-type DVD-R (step S79; NO), according to the first type information 145, the currently loaded DVD is DVD-R1R ′. Although it is determined that it is neither G-type DVD-R nor A-type DVD-R, in this case, the optical disc may be an optical disc formed by illegally copying recorded information. Since the reproduction performance is high, the reproduction process for the optical disk is immediately stopped (step S31), and the optical disk is ejected from the information recording / reproduction apparatus (step S32), and the reproduction process is terminated.

  On the other hand, if it is determined in step S79 that the currently loaded DVD is an A-type DVD-R (step S79; YES), then the recorded information recorded in the DVD is reproduced (from the A-type DVD-R). Is detected (step S34), and it is further confirmed whether or not the encryption processing is performed on the recording information recorded on the A-type DVD-R (step S80). If it is encrypted (step S80; YES), the recorded information is protected by the copyright law, and the reproduction process for the DVD-R1R ′ is immediately stopped as it should not be reproduced (step S80). In step S31, the DVD-R1R ′ is ejected outside the information recording / reproducing apparatus (step S32), and the reproduction process is terminated. On the other hand, when the DVD-R1R ′ is not encrypted (step S80; NO), The characteristic information CP is extracted from the sector information ST in the recording information recorded on the A-type DVD-R, and it is confirmed whether or not the content of the type information ADP included therein is “01b” (Step S81).

  If the content of the confirmed type information ADP is “01b” (step S81; YES), as described above, the type information ADP is not defined in the read-only DVD and the A-type DVD-R. (Refer to FIG. 11) Since the content confirmed in step S79 is an A-type DVD-R and its type information ADP is “01b”, in this case, some sort of illegal processing has been performed. Assuming that there is a possibility that the DVD-R is currently loaded, the reproduction process for the optical disk is immediately stopped (step S31), and the optical disk is ejected outside the information recording / reproducing apparatus S (step S32), and the reproduction process is terminated. .

  On the other hand, if it is determined in step S81 that the content of the confirmed type information ADP is not “01b” (step S81; NO), it is assumed that a regular A-type DVD-R is currently loaded. It is determined whether or not the second type information 88 in the DSI data 51 is “00b” (step S82).

  As a result, when the second type information 88 is “00b” (step S82; YES), the reproduction processing is continued assuming that a regular A-type DVD-R is currently loaded in the information recording / reproducing apparatus. In addition, it is confirmed whether or not an operation for stopping the reproduction process has been executed in the operation unit 133 (step S36).

  When the stop operation is not executed (step S36; NO), the process returns to step S34 to continue the reproduction process, and the value of the second type information 88 in each DSI data 51 sequentially obtained as the reproduction is continued. On the other hand, when the stop operation is executed (step S36; YES), the reproduction process is stopped as it is (step S30), and the series of reproduction processes is terminated.

  On the other hand, if it is determined in step S82 that the second type information 88 is not “00b” (step S82; NO), the type and second type information of the optical disc indicated by the first type information 145 in the currently loaded optical disc. Since the type of the optical disk indicated by 88 is not different and there is a high possibility that this optical disk is an optical disk formed by illegally copying recorded information, the reproduction process for the optical disk is immediately stopped ( At the same time as step S31), the optical disk is ejected from the information recording / reproducing apparatus (step S32), and the reproducing process is terminated.

  In step S82 shown in FIG. 14, the same judgment as in step S17 shown in FIG. 9 is performed despite the fact that the currently loaded judgment is the A-type DVD-R. This is the same as in the case of step S17 in FIG.

  On the other hand, in the determination in step S76, the content of the first type information 145 is either “0001b” or “0011b” (step S76; YES), or the currently loaded DVD in the determination in step S78. When it is confirmed that -R1R 'is a G-type DVD-R (step S78; YES), playback of the recorded information recorded on it (detection from the DVD) is started (step S34). Further, it is confirmed whether or not the encryption process is performed on the recording information recorded on each DVD (step S83). If the recorded information is encrypted (step S83; YES), the recorded information is protected by the copyright law and should not be reproduced, and the reproduction process for the DVD is immediately stopped (step S31). The DVD is ejected to the outside of the information recording / reproducing apparatus (step S32), and the reproducing process is finished. On the other hand, when the DVD is not encrypted (step S83; NO), it is recorded on the loaded DVD. The characteristic information CP is extracted from the sector information ST in the recorded information, and it is confirmed whether or not the content of the type information ADP included therein is “01b” (step S84).

  If the content of the confirmed type information ADP is not “01b” (step S84; NO), the type information ADP is defined only in the DVD-RW, DVD-RAM, or G-type DVD-R as described above. (See FIG. 11), the content confirmed in step S76 or S78 does not match the content confirmed in step S84. In this case, an optical disk that has been subjected to some unauthorized processing may be currently loaded. Since the reproduction process for the DVD is immediately stopped (step S31), the DVD is ejected from the information recording / reproduction apparatus (step S32), and the reproduction process is terminated.

  On the other hand, when the content of the confirmed type information ADP is “01b” (step S84; YES), the content confirmed in step S76 or S78 is appropriate as a regular DVD-RW, DVD-RAM, or DVD-R. Then, it is determined whether or not the second type information 88 is “01b” (step S85).

  As a result, when the second type information 88 is “01b” (step S85; YES), the G-type DVD-R, DVD-RW, or DVD-RAM that is currently capable of reproducing the recorded information normally can be used. The reproduction process is continued assuming that one of them is loaded in the information recording / reproducing apparatus, and then it is confirmed whether or not an operation for stopping the reproduction process is executed in the operation unit 133 (step S40).

  When the stop operation is not executed (step S40; NO), the process returns to step S38 to continue the reproduction process, and the value of the second type information 88 in each DSI data 51 sequentially obtained as the reproduction is continued. On the other hand, when the stop operation is executed (step S40; YES), the reproduction process is stopped as it is (step S30), and the series of reproduction processes is terminated.

  On the other hand, if it is determined in step S85 that the second type information 88 is not “01b” (step S85; NO), the type and second type information of the optical disc indicated by the first type information 145 in the currently loaded optical disc. Since the type of the optical disk indicated by 88 is different, and it is highly likely that this optical disk is a DVD formed by illegally copying recorded information, the reproduction process for the DVD is immediately stopped (step S31). And the DVD is ejected outside the information recording / reproducing apparatus (step S32), and the reproducing process is terminated.
