Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an audio reflex system, in particular for displaying an image related to an A-dio signal separately from an audio A1 word. This invention relates to an audio record disc on which a computer program is recorded.

PRIOR TECHNOLOGY Conventionally, video signals have been recorded on the same track (hereinafter referred to as S't) on the same track of a disc-shaped recording body, such as A1Δ. In order to be able to playback video signals with a much wider band than normal video signals for approximately 60 minutes per side of a disk, information signals are recorded as intermittent bit strings on a disk that rotates at high speed, and at extremely fine track pitches. It is well known that the existing audio record discs on which analog audio signals are recorded and the above-mentioned video discs are different from each other.
The signal recording format, disc rotation speed, signal reading and playback format, etc. are completely different, and existing record players cannot play video discs.

However, even when playing the audio disc record on an existing record player, if image information related to the audio signal can be obtained, it can play an auxiliary role to help the listener's imagination. It has been desired to be able to reproduce continuous image information.

SUMMARY OF THE INVENTION In order to meet the above requirements, it is an object of the present invention to provide an A-dio disc record in which a computer program for causing a microcomputer to display an image related to an audio signal is recorded at a predetermined location.

Means for satisfying the above requirements The present invention provides an area in which audio (No. 5) is recorded,
The device is configured such that a computer program for displaying an image related to an audio signal by a computer is stored in each area, and one embodiment thereof will be described below with reference to the drawings.

Embodiment FIG. 1 is a plan view of an embodiment of the audio record disc according to the present invention, and FIG. 2 is a partially enlarged plan view of the 11 audio record disc shown in FIG. Audio record disc (hereinafter referred to as "disc")
For example, a non-recording zone 3 is shown on the inner circumferential side of an audio signal recording area 2 in which an analog audio signal is converted into mechanical vibration and recorded on a spiral track as in the past. As shown by hatching, a computer program recording area 4 is formed in which a computer program is recorded in a spiral track. A non-recording zone 6 is also provided between the computer program recording area 4 and the record pool 5. Also, 7
is the center hole of the disk 1. Note that the first
On the side (A side), only an audio signal recording area is formed in which analog audio signals are recorded in a spiral trunk in exactly the same way as in the conventional case.

In the computer program recording area 4, the titles of all the songs of the A-D A signal recorded on the disk 1, necessary graphics screens, performer names, lyrics and guitar chords of each song are stored using a microcomputer. A computer program for displaying the image on a display device is recorded. The signal waveform of this computer program is such that the binary original digital data shown in FIG. For example, the pulse frequency shift keying (F
SK) has a signal waveform as shown in FIG. 3 (13), and when using the above p c -gooi, the baud rate of digital data is GOObps.

Therefore, when the computer program recording area 4 is played back, the CONVUTAB 1:1 gram signal is not an audio signal even though it is a signal in the audible frequency band, so it is an extremely harsh noise and is emitted from the C speaker. It ends up. For this reason, it is necessary to record separately from: 1. the audio program recording area; 1.1 the audio program recording area; The computer program must be recorded as an audio signal in a location where it is difficult to reproduce it by mistake. Therefore, in this embodiment, as shown in FIG. 1 and FIG.
The recording is formed at the innermost circumference position of the second side where it is least likely to be played back accidentally as an audio signal.Then, after the last song in the audio signal recording area 2 of the second side is finished, the computer program The recording area 4 will not be corrupted during playback. As shown in Figure 2, the audio signal recording area 2
The track is formed so that it reaches the concentric j-rahinoino (final groove) 9 through the last groove after the end of the last song. ) Play to Record 1 After the last song has finished playing, the playback needle of A7 is also sent when it is placed in the 7 position)) Through item 8 - Cm center circle 1 to rack 9 trace 1 sell 1 no, computer Program description),? Continuously reproducing area 4 is 4.
c On the other hand, computer program writing (7, 17-j
In this case, the wider the area from -1 to the inner part is, the wider the range in which the unit can be lowered onto the disk 1, making it easier to play. As shown, from the introduction groove 10 of the computer program recording area 1 to the rack, the computer program recording area 2 is relatively wide for the first 1 to 1 to 100 m (2 to 10 m); , in FIG.
Overturning the final groove of the 1 gram recording track.

Next, the recording system of the inventive record disc will be explained with reference to FIG. In the same figure, Mike [1] Mbi” - Yu 13 is Mpi 1? Generate the 4-day A message (2-related images to the microcomputer) and display it on the rezo display device. - Replay the master tape on which the analog audio A1 word to be recorded has not been recorded.
The signal is supplied to the horn head 16 via the amplifier 1b. As a result, the reproduced analog Δ-gay'4 signal is converted into mechanical vibrations on the vehicle panel 17 and is transmitted in a spiral trunk. The computer program signal shown in FIG. 3(B) taken out from the microcomputer 13 is supplied to the cutter head 16 via the amplifier 15, or is once recorded in the cheap recorder 14 and further reproduced to the amplifier. 15, it is supplied to the cutter spatula 1ζ16, and is applied to the recording master 17,
It is recorded forming a shape of 1 square. The recording source 2 disk 17 is made into a standby by a well-known disk making process, and then the audio record disk 1 as shown in FIGS. 1 and 2 is reproduced in large quantities using this as a base.

In addition, in this recording process, it is necessary to ensure that the recording time of all songs of audio signals does not exceed the maximum time that can be recorded on the disc, taking into consideration the computer program recording time. As shown in the figure, concentric tracks 9 are formed, and then a lead-in portion is made relatively wide to form a computer program recording area 4.
In order to form the laces, it is easy to manually cut the laces on these parts using J5. Further, the computer program signal is recorded at a predetermined level so that the computer program signal reproduced from the disk 1 can be used to read the microcomputer.

Next, to explain the playback system of the audio record disc according to the present invention, FIG. First, the computer program recording area 4 is played back.As a result, the [1-tab] [1-gram] word taken out from one record player as shown in FIG. 3(B) is amplified by the amplifier 20. After that, the data is supplied to the microcomputer 21, and is also supplied to the cassette recorder 22 as necessary for program preservation, etc., and recorded on the cassette database. The 1 gram number on the computer tab is connected to the bus 2/2 through the interface 23 in the microcomputer 21.

Once completed, the keyboard 30 is operated next. As a result, the microcomputer 21 generates both edge signals according to the input reproduction computer program, and displays the signals on the dedicated monitor 35 or R
The F modifier 3G allows the specified TV program to be sent to A.
The signal is converted into a 7-channel signal band and supplied to a general commercially available color television reception example (general color TV) 37 to display, for example, tiles 1 to 3 of the disk 1 and required graphics images, and further, for example, as shown in FIG. Display the menu screen as shown in .

While looking at the screen shown in FIG. 6, the listener of disc 1 operates the keyboard 30 to select, for example, (R) on the screen, and the person who recorded the audio A signal on disc 1 or the performer When you press 3"A IR7 on the screen where the names of the people who smoked this computer program in sequence [this switch and the squares on the screen], the screen changes to the screen where the names of the people who smoked this computer program for 1'1 time are displayed. , all on both sides of disk 1 -C9

), and when the first song starts playing, at 01, cut to the image that says ``Key power is required''. Following this image, the listener then operates the record I-play ψ19 to engage the playback needle in the introduction groove of the first song on the first side of the music screen 1.
Thereafter, when the song is sounded from the speaker 38, the keyboard 30 is operated at the same time. Then, the microcomputer 21 switches the playback screen and displays images related to the first song one after another in accordance with the progress of the playback of the first song.

The picture ('4:) related to this first song is, for example, the guitar chord and lyrics, and as the song progresses, the guitar chord and lyrics are displayed in parallel in sequence (however, in the accompaniment part, only the guitar chord is displayed). ).

Here, no means is used to synchronize the sound played from the disc 1 by the microcomputer 21 and the record player 19, but since the playing time of the song and the point in time when the lyrics are played are known in advance, The computer program is created so that the desired image is displayed depending on the desk.

Further, a computer program is created for each song, and when the reproduction of the first song is finished, the double-sided screen is switched again to the screen shown in FIG. 6. If you want to play the second song next, operate the “2” switch on the keyboard 30,
Thereafter, in the same manner as above, when the second song is sounded from the speaker 38, by operating the keyboard 3o to the same verse,
On the playback screen, necessary images are sequentially displayed as the playback of the second song progresses.

J5, for example, 5 songs on the first side of disc 1 and 4 songs on the second side.
The music program of the song is recorded, and if you want to play the first song on the second side again, you will have to select the 6th song. By performing the same operations as described above, images unique to the song are sequentially displayed on the dedicated monitor 35 or the general color TV 37 as each note of the arbitrarily selected song is played.

As an application example, the present invention is not limited to the above-described implementation (Il), and various other variations of images related to menu screens and songs can be considered.

Also, there are other discs on which only the audio delta flame number is recorded in 71C ((!+lI is a disc of optical a'', tori!S!l, where digital A・-j Io Shinkyu is recorded in the constant velocity method) It can also be applied to -C.

In addition, the above-mentioned combination "-Tab 1] Durham 5 I-C area 4 η people) If you record an announcement such as "Please be careful as you will hear an unpleasant sound if you listen to A311", the possibility that this area will be played back by mistake will be further reduced.

Furthermore, if the playback device is capable of performing a muting function, if a signal for triggering this muting is input into the introduction groove, this area will not be played back.

Note that if it is necessary to reproduce this area, a function for removing this muting may be provided on the playback device side, and the muting may be removed.

Furthermore, in the case of a 17 cm disc, for example, the computer block may be recorded on the entire surface of one side of the disc.

Effects As described above, the present invention includes a computer program that causes a computer to display an image related to an audio signal on a display device, so no changes are required to the existing audio record disc playback system. You can add an image related to the audio signal in the combination and display device without bringing the audio signal recording area and the monitor block l\ recording area. Since a concentric track is set between the A and D signals, even if the playback is left as it is after the playback of the A signal is completed, the playback button will continue to trace this concentric track and record the Convenience Store 1 tab program by pressing L and J. Therefore, it is possible to prevent the computer program signal from being emitted as noise from the speaker, and furthermore, the computer program recording area is further away from the audio signal recording area. 1] of the program to the microcomputer is also recorded together on the inner circumferential side.
-1~ is easy to do, and it can be mistakenly used as an audio signal.
This has the advantage of being able to substantially prevent computer programs from being played back.
