Description

1307497 15761pif.doc IX. Invention Description: This case is based on the Korean Patent Application No. 2003-96223 and the January 2004 issue of the Korean Intellectual Property Office on December 24, 2003. The priority of Korean Patent Application No. 2004 6471, the entire disclosure of which is hereby incorporated by reference. BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a method and apparatus for recording data to a write-once disc and reproducing data from the disc, and more particularly to recording access on a write-type disc. Information for faster access to information that requires the use of write-once discs, as well as writes to 'one-time discs' using the above methods and apparatus. [Prior Art] New information can be repeatedly recorded on a rewritable disc on which information has been recorded. However, when recording new information on a write-once disc, since the recorded information can neither be erased nor repeatedly recorded in the location where the green information is recorded, a new location must be assigned in order to update the recorded information. . Usually 'only the information that is ultimately updated makes sense. Therefore, in order to read the information that is finally updated, an update area is allocated to the data area, and the disc drive guesses the information that is finally updated by searching for the update area of the update information. When a large amount of information is recorded in this update area, it takes a lot of time to detect the information that you want. On a write-once disc that performs defect management by the drive. When a write-once disc is being used, an area for recording defect management information 1307497 15761pif.doc is generated, and there is an instruction to write the person-time. Information on the status of the disc. Unlike the rewritable discs, depending on the characteristics of the write-sub-disc, when the defect management information needs to be updated, since the update information cannot be repeatedly recorded and the location of the existing information is recorded, the updated information must be recorded in an empty position. Therefore, a relatively wide update area is required. Usually, the update area is assigned to the lead-in area or the lead-out area. However, the 'updated area' can also be assigned to the data area in order to increase the update count based on the user's mosquitoes. When the information that is required to be written to the one-time disc is finally updated and updated in the update area allocated to the ugly, #finally updated (four) includes the information and indications that are not assigned to the #料区When updating the information of the location of the zone: even if all the update zones assigned to the guide zone or the lead-out zone are arbitrarily, the information of the final reduction of the asset reduction record that is finally updated cannot be revoked. A human-secondary disc with the information recorded on the disc. When the data is passed through the information, the access information required by the reader is updated. The one-person method is proposed. Device, through this method: information; two-time disc when 'reading the required method and device to be installed, through this method of accessing the time disc used for new information, the reader needs to be replaced The invention proposes that a record type writes a one-time disc having at least one 1307497 15761 pif.doc ϊ 斤 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' '斤的-贝讯所Access information in the update area.

I have set it up, and I have proposed one, f, and the data recorded on the one-time disc. 2 tongue write 'read single 兀' writes the information on the write-once disc; controller, control write / The reading unit records the predetermined update capital in the one of the plurality of update areas allocated to write a disc: save = give =, at least one of the access information areas of the slice records the information of the final update. Further, a method for reproducing a human-sub-disc is provided, which is provided with at least one access information area for writing a one-time disc to obtain new access information; and obtaining an indication from the finally updated access information. The information of the update area in which the access is located is updated, and the final update access is recorded in a plurality of update areas assigned to the write-sub-disc. The invention further proposes a device for reproducing a write-personal disc, a package, a reader, a data recorded on a person-recorded disc, and a control-controlled side reader from being assigned to a write-disc disc.

The above and other objects, features and advantages of the present invention will become more <RTIgt; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Reference will now be made in detail be The embodiments are described below, and the present invention will be explained with reference to the drawings. 1A and 1B are diagrams showing the structure of writing a one-time disc in accordance with an embodiment of the present invention. Fig. 1A is a structure of a write-once disc having a single recording layer, and Fig. 1B is a structure of a write-once disc having a double recording layer. A write-once disc having a single § recording layer includes a lead-in area, a data area, and a lead-out area arranged from the inner ring to the outer circumference. The write-once disc having a double recording layer has a first recording layer L0 and a second recording layer u' each including: a lead-in area from the inner ring, a data area, and a lead-out area. 2 is a detailed structure of a write-once disc having a single recording layer in accordance with an embodiment of the present invention. Referring to FIG. 2, the lead-in area includes a first disc management area (DMA1), a second disc management area (DMA2), a first temporary, a slice management area (TDMA1), an access information area (AIA), and a recording condition test. Area. The export II includes a third disc management area (DMA3) and a fourth disc management area (DMA4). In addition, the 'export area can include at least one temporary 1307497 15761pif.doc defect management area, recording condition test area and AIA. That is, at least one of the aia, DMA, TDMA, and § conditional test areas is at least one wrapped in the lead-out area. 3/ and 3B are detailed structures of a write-semi-disc having a double recording layer in accordance with an embodiment of the present invention. Fig. 3A is a view showing the structure of the first recording layer L〇, Fig. 3B, and the structure of the recording layer L1. The structure of the first recording layer L0 shown in Fig. 3A is the same as that of the write-type disc having a single recording layer as shown in Fig. 2. The structure of the second recording layer u shown in Fig. 3B is similar to that of the second recording layer L0. However, in the structure of the second recording layer u, the AIA is not assigned to the second internal area, and two TDMAs are allocated to the second data area. A write-once disc with a dual recording layer includes five TDMAs, TDMA1 to TDMA5. The location and size of TDMAi and TDMA2 are well known recording and reproducing devices. However, when disc initialization is performed using a write once disc having a double § recording layer, TDMA3 ' TDMA4 ' TDMA 5 is assigned to the data area by the user or recording device, and/or the reproducing device. The temporary disc defect structure (TDDS) is recorded in TDMA1 when the temporary disc management structure (TDMS) is recorded from TDMA1. This TDDS includes the size and position of the TDMA allocated to the data area. 4A and 4B are detailed structures of a write-once disc having a dual recording layer in accordance with another embodiment of the present invention. Fig. 4A is a structure of the first recording layer L0. Fig. 4B is a structure of the second recording layer L1. The write-once disc with double recording layer shown in Figs. 4A and 4B is assigned 1307497 15761pif.doc TDMA1 'TDMA2 and TDMA5. That is, in addition to the known TdMA1, TDMA2, when disc initialization is performed using a write-once disc having a dual recording layer, only the TDMA 5 is allocated to the second data area by the user or the recording device, and/or the reproducing device. . A method of recording data in areas and areas such as TDMA for writing a one-time disc will now be described. TDMA is the area in which the TDMS used to write the one-time disc management is recorded before the write-once disc is initialized. The finalization of writing a one-time disc is to prevent the write-once disc from being recorded again. When the user's option can no longer record the data day τ on the write-once disc, or when the data is not additionally recorded on the write-once disc, the one-time disc is terminated. The TDMS includes a Temporary Defect List (TDFL), a TDDS, and a Free Bit Map (SBM). The TDFL includes information indicating an area in which the defect is generated and a resource management TDFL indicating the replacement area, including a position indicator indicating the location where the TDFL is recorded, and a position indicator indicating the location where the SBM is recorded, indicating the position and size of the remaining area allocated to the data area. Capital

Information indicating the location and size of the TDMA assigned to the data area. The SBM table does not record the state of the one-time disc recording bit map by assigning different bit values to the duster. This cluster includes the cluster in which the data is recorded in the cluster unit, that is, the data recording unit, and Record a collection of data. When writing a write-once disc to a recording device and/or a regenerative device, in order to use the write-once disc in the device, the TDMS, especially TDDS, which is updated with the final 1307497 15761pif.doc, will soon be required. Generally, when a write-once disc is loaded into a recording device or a reproducing device, the recording device and the reproducing device decide how to manage the write-type disc and how to read the information from the lead-in/export area. Record or regenerate data. If the amount of information recorded in the lead-in/export area is large, more time is required to prepare for recording or reproduction after loading the write-once disc. Therefore, using TDMS, the TDMS recorded when the data is recorded on or reproduced from the one-time disc is recorded in the TDMA, and the TDMA is distinguished from the defect management and assigned to the lead-in/export area. When writing a one-time disc end, 'by allowing the recording or reproducing device/defect management area to read meaningful information, storing only the last meaningful information in TDFL and TDDS' and being updated and recorded multiple times in the DMA It is possible to use a write-once disc for information access very quickly, and the TDMS recorded in the TDMA, ie TDFL and TDDS, is finally recorded in the DMA. Figure 5 illustrates a method of recording data in a user profile area and a remaining area in accordance with an embodiment of the present invention. Referring to FIG. 5, A indicates a user data area, and b indicates a remaining area. The method of recording user data in the user data area includes a continuous recording mode and a random recording mode. In the continuous recording mode, the user data is continuously and sequentially recorded 'and in the random recording mode, it is randomly recorded. Areas 1 through 7 indicate the units to be verified after the record is executed. The recording device writes the user profile in the area 1 to verify whether the user profile is normally written or has a defect in the area 1. If a partial defect of 12 1307497 is found, this part is indicated as the defective area, ie the first defect. In addition, the recording device rewrites the user information written in the first defect in the remaining area. The part of rewriting the user data that has been written in the first defect is called the first substitution. The recording device writes the user profile in area 2, verifies whether the user profile is normally written or has a defect in area 2. If a partial defect is found, this portion is indicated as the defective area, i.e., the second defect ^ is the same, resulting in a second substitution corresponding to the second defect. Also, in the area (D, the third defect and the third substitution are generated. In the region 4, φ is not found due to the defects, so there is no defective area. TDDS 'These defects are in the area 1 to Defect zone generated in 4. 2 from

After the user&gt; is written and verified, if the end of the first recording operation is predicted, if the user presses the "Popup, Button, or User Data assigned to the recording operation has completed the recording, the recording device writes in the TDMA. Information about the defects of No. 〆, No. 1 defect and No. 3 defect as the first-segmentation, the end of the fifth record operation 13 1307497 15761pif.doc 'The recording device writes the defect No. 4 in the TDMA, The resource of the fifth defect is used as the first TDFL. In addition, the management structure for managing the second TDFL is written in the TDMA as the second TDDS. As shown in FIGS. 2 to 4, when multiple write-once discs are allocated In the case of TDMA and the remaining area, the tdma and the remaining area are used in a predetermined order. In the case of '=', as shown in FIG. 3, the data write path applied to the write human disc having the double layer recording layer is reversed. The magnetic path, that is, in this path, the data is from the first inner region of the first recording layer to the first outer region of the first recording layer L0, and from the second inner region of the second recording layer L1 to the first. Recorded in the first outer zone of the recorded layer L1, this At the time, the data of the remaining area is recorded from the first remaining area of the first recording layer L0. When the first remaining area is full, the second remaining area, the third remaining area, and the fourth remaining area are used in order. TDMS is recorded from TDMA1 of the first recording layer. When TDMA1 is full, 'the updated TDMS is recorded in TDMA2 assigned to the second internal area from the second recording layer u. When TDMA2 is full' The newly updated TDMS is recorded in the TDMA 3 allocated from the first material area of the first recording layer L0. In the present embodiment, TDMA1 and TDMA2 assigned to the internal area of the recording layer are preferably written for the one-time disc. However, the TDMA allocated to the data area may or may not be allocated by the user option. Therefore, when the TDMA allocated to the internal area of the recording layer is full, 'the tdma assigned to the data area is used. When assigned to the data area When the final updated TDMS is written in the TDMA, the write once disc is removed and reloaded into the recording device. 1307497 15761pif.doc In order to use the write once disc, the recording device must obtain the final update. TDMS. However, in points The TDMS is recorded in the TDjvlA of the data area until the disc drive accesses the TDDS contained in the TDMS, and the disc drive can recognize the fact that the TDMS is recorded in the tdMA allocated to the data area. To solve this problem, the AIA is separately Assigned to the predetermined position of the write-type disc of the present invention. The access information (AI) is recorded in the AIA. The AI indicates the location where the update information such as the TDMS is recorded. Also, the update information indicates the initial period of the Xin in order to use Write information that the disc must be recorded and/or must be recognized by the regenerative device. The initial period is when the write once disc is loaded to the recording and/or reproducing device. In addition, the area in which the record update is based is called the update area. In this embodiment, the updated information represented is TDMS, and the update area represented is TDMA. As shown in Figures 2 through 4, the predetermined position at which the AIA is assigned to the lead-in area or the inner area is (4) but not necessarily. In addition, (4) restricts aia's =, 'but is not necessary by minimizing the number of AIs recorded in the AIA and the number of AI updates, because it takes a long time if the AIA is large or assigned an AIA. Time to get AI. The secondary drawing 6 is the second access information (AI) according to the first embodiment of the present invention; The AU shown in Fig. 6 shows the AI in the write-sub-disc with the double recording layer as the TDMS for updating the information, the TDMA for the update area, and the TDMA shown in the third. Referring to Figure 6', the AI header includes an AI identification symbol indicating that the subsequent bead is an AI, and the AI update count, which indicates the update count of the UI. 1307497 15761pif.doc The AI includes the total number of TDMAs assigned to the write-once disc, indicating the information of the TDMA where the final TDDS is located, indicating the location of the TDMA location. Each TDMA location information may include information indicating the start and end positions of each tdmA, or information indicating the start and end position and size of each TDMA. Since the TDDS includes a pointer indicating the position of the corresponding tdfL, the AI includes information indicating the TDMA in which the final TDDS is recorded. When the write-once disc according to the present invention is loaded into the disc drive, the disc drive can obtain the final updated AI by the AIA in the known position to identify the TDMA where the final TDDS is recorded. The disc drive gets the final TDDS from TDMA. In order to reduce the access time required to obtain the final gossip recorded in the AIA, it is preferable that the gossip is continuously recorded in the AIA in the continuous recording mode, and the number of AI updates is minimized, but this is not essential. In accordance with an embodiment of the present invention, in order to minimize the number of AI updates, the AI is updated whenever the TDMA in which the final TDDS is located changes. In addition, when the information indicating the number of TDMAs allocated to the write-once disc and the information indicating the position of ==dma are included in the AI, the AI is also updated when the information of the new TDMA or the TDMA position is changed. In addition, it is preferable to repeatedly record the same AI so that it is prepared when an error occurs in the recorded AI, but this is not essential. ♦Because the AI to be updated is continuously recorded in the previous ai, even if: the information indicating the detailed address of the final TDDS is not included in the ai fear due to the RF signal obtained from the recorded data area and the non-recorded There is a difference between the RF signals obtained by the material zone 16 1307497 15761pif.doc, and the recording device and/or the reproducing device can quickly use the track jump method by identifying the boundary between the recorded data area and the non-recorded data area. Look for the location where the final TDDS is recorded. Figure 7 is a diagram showing the structure of access information in accordance with a second embodiment of the present invention. The AI shown in Fig. 6 includes information indicating the position of all TDMAs and information indicating the TDMA in which the final TDDS is recorded. However, the AI shown in Figure 7 includes information indicating the location of the TDMA where the final TDDS is recorded. The information indicating the location of the TDMA where the final TDDS is located may be represented by the address of the first physical magnetic zone of the first cluster of TDMA and the address of the physical magnetic zone of the last cluster of tdMA. However, any person skilled in the art can make various changes to the present method without departing from the spirit and scope of the present invention. This method is information indicating the location of the TDMA where the final TDDS is recorded. Figure 8 is a diagram showing the structure of access information (AI) in accordance with a third embodiment of the present invention. The AI data structure shown in Figure 8 is the same as the TDDS data structure. That is, using TDDS as an AI does not require defining a separate AI data structure. In order to use the TDDS as the AI, information indicating the location of the TDMA where the final TDDS is located must be blocked from being added to the TDDS. Figure 9 is a diagram showing the structure of access information (AI) in accordance with a fourth embodiment of the present invention. The AI data structure shown in Fig. 9 is the same as the data structure of the TDDS described in the third embodiment. However, unlike the third embodiment, the flag indicating the location of the TDMA where the final TDDS is located is further included in the TDDS. In this embodiment, the flag consists of 8 bits, and 5 bits from b〇 to 17 1307497 15761pif.doc 指示 indicate the TDMA where the final TDDS is recorded, and the 3 bits from b5 to b7 are reserved bits. yuan. For example, when b0 to b4 are "00001b", it is possible to define that the final tdDS is recorded in TDMA1, when b0 to b4 are "00010b", it is recorded in TDMA2, and when b0 to b4 are "00100b", it is recorded. In TDMA3, when b0 to b4 are "01000b", it is recorded in TDMA4, and when b0 to b4 are "10000b", it is recorded in TDMA5. According to the present embodiment, a plurality of TDMAs assigned to write one-time discs are continuously used based on the data recording direction. Therefore, considering a plurality of physical TDMAs as one continuous TDMA, one continuous TDMA can be divided into a plurality of virtual TDMAs. Figure 10 is a data structure obtained by dividing a complete TDMA into a plurality of virtual TDMAs. For example, in a write-once disc having a dual recording layer, when tDma is used in the order of TDMA1, TDMA2, TDMA3, TDMA4, TDMA5, if each of TDMA1 and TDMA2 includes 2048 clusters, TDMA3 and TDMA4 Each includes 4096 clusters, τχ)ΜΑ5 includes 8192 clusters' The entire TDMA includes 20480 clusters. If the entire TDMA is divided into 512 clustered units, 1024 clustered units, and 2〇48 clustered units, the entire TDMA can be divided into 40, 20, or 1 virtual TDMAs. If the size of TDMA1 allocated to TDMA1 to TDMA5 written to the one-time disc is very large, if the final TDDS is recorded in TDMA3, the recording/reproducing device recognizes from the AI that the final TDDS is recorded in TDMA3, via Look for TDMA3 and get the final 18 1307497 TDDS. However, when TDMA3 is very large, it takes a long time to find TDMA3 in order to get the final TDDS. Therefore, in order to solve this problem, the concept of virtual TDMA described above is utilized. The size of each virtual TDMA can be the same as that shown in FIG. However, the size of each virtual TDMA is not limited to this embodiment. TDMA, new Φ Φ, recording/reproducing device divides the entire TDMA into multiple virtual AIs when recording the virtual TDMA changes in which the final TDDS is located. Each of the data structures according to the second to fourth embodiments can be used as the AI data structure of the present embodiment. However, the AI of the present embodiment includes information indicating that the virtual TDMA in which the final TDDS is located, or information indicating the location of the virtual TDMA in which the final TDDS is located. Figure 11 is a block diagram of a recording apparatus in accordance with an embodiment of the present invention. Referring to Figure U, the recording device includes a write/read unit i, controllers 2 and . Have hidden body 3. Write/manufacture i writes data on the write-sub-disc, reads the recorded data 'verifies whether there is a defect in the recorded material: assigns the AIA according to the present invention to the write-once disc view . In order to manage the defect, the controller 2 uses the "post-write check" method, which is a method of making a defect through the data in the pre-(four) unit.

In the present embodiment 20 1307497 15761pif.doc, the information to be updated indicates a TDMS. When TDMs are generated, the TDMS is temporarily stored in the memory 3. When the recording operation is completed, the controller 2 reads the TDFL stored in the memory 3, and supplies the TDFL· to the write/read unit f, and the write/read unit 1 The TDFL is written in one of the plurality of update areas assigned to the write once disc 100 in operation 75. In this embodiment, the update area indicates a TDMA. ,

The controller 2 determines in operation 77 whether there is another recording operation. If there is another recording operation, operations 71 through 77 are repeated. If there is no other operation, the controller 2 determines whether it needs to update the AI in operation 79.
