Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an information signal recording disk reproducing device, and in particular, it is capable of processing pixel data groups related to still images and signal data such as audio signals and computer control programs [1 gram]. The present invention relates to an information signal recording disk reproducing apparatus for reproducing already recorded signals of an information signal recording disk in which signals are synthesized and recorded in chronological order on the same track.

(Prior Art) Conventionally, analog information signals such as composite video signals and audio signals have been subjected to frequency modulation (FM) and recorded on concentric or spiral tracks, for example, as changes in geometric shapes. Information signal recording disks (hereinafter referred to as disks) are known.

This disc is called a video disc because the recorded information is mainly composed of composite video data.
On the rack, the yQ transmission wave is modulated with an analog information signal, and the composite video data is recorded in the form of a curved harmonic signal obtained by analog modulation and 1r7. J5, for example, an address signal for random access is recorded in a specific period within the vertical blanking period of a composite video signal, and the address signal is a coded digital signal. However, since the main body of recorded information is analog-modulated composite video signals, etc., tracks such as the recording track of this video disc will be referred to below as
Tree I! In the IJ specification, this will be referred to as an analog L1 recording track for convenience.

On the other hand, the audio signal or the audio 438 and the video signal are digitally modulated to a large extent, are synthesized in time series, and are recorded on a concentric rack (J, 1c is a spiral), for example, as a change in geometric shape. The disk f disk described above is also known from the prior art. The recorded information on this disc is mainly audio signals, and the video signals are mainly static images and d'r and serve as auxiliary information to aid the imagination of audio No. 131 listeners. It is called a digital audio disc because it is just a disc. This digital A-5'
=r On the recording track of the Odesk, an information signal such as 71 voice signal 8 is digitally modulated and converted into a digital signal form, and then frequency modulated (F M )? 9 and recorded.

Hereinafter, Honkawa 111tJ distributes 5 tracks for digital recording, such as the recording tracks of this digital audio disk.

By the way, the above-mentioned video disc has a scanning sword electrode, as proposed by the applicant! The recorded video is played back by detecting the change in capacitance formed between the
In addition, a reference signal for ranking control of a violet frequency is recorded on both sides of the information (I record 1-T/knock analog recording track), and this reference signal is used during playback. 1. A video disc is known that eliminates the need for the 11 guide fM by comparing novels and performing tracking control.

On the other hand, among the above-mentioned digital A-', i'''r, and 4arsk, as proposed by the applicant I'; The reference signal for the l-ragging position is recorded on both sides of the information (Lii, 5i3 recording) - on the knock (digital signal recording 1 Herak), and the capacitance JV1 change reading tension 1 digital audio disc without button guide groove is It is known that this digital audio disc is rotated during playback at the same number of revolutions as a series of capacitance change readable video discs, and the track 4 is rotated during playback.
The frequency and reproduction method of the reference signal 53 for RI 11 are the same, and the capacitance! It is also the same that the already recorded signal +3 is read by detecting a change in lit: l:+5. For this reason, the Pino 2,1FJ1R disk playback device plays back this digital A-J゛Io disk, and also the Ic133 and Video Disc II before and 111.
As shown in the figure, the scanning mechanism is able to properly perform the tracking operation, and the scanning of A? ! 1 to 3 can be picked up and reproduced, and by supplying the reproduced signal to the adapter, the original 8 signal etc. can be tuned to 1u.

Therefore, the above-mentioned capacitance change reading type video disk and capacitance change reading type digital audio disk proposed by the present applicant are the same capacitance change reading type video disk. The above-mentioned digital audio 7j disk and video disk have the advantage that they can be played back using a shared device, and the so-called 7i 111 playback is possible.

However, the above-mentioned video data C disk and the gamma digital A-dio disk are separate lJs, even independent disks, and the above-mentioned compatibility cannot be said to be compatibility in the strict sense. On the other hand, γ-digital A-dio discs (compared to video discs, the green signal mentioned above is a digital signal, and due to the characteristics of digital signal transmission, the sound pli signal is distorted over a wide dynamic range and reproduced with high fidelity. ,Also,
It is a still image and is extremely clear, and of course it has the advantage that the audio signal is reproduced at a super high level of 7.5 A along with the internal image of the still image.

On the other hand, for video discs, 11−both iQ′ <l
Since the same track is played repeatedly on 1111, it is generally not possible to play back still images and sound at the same time as with digital Δ-A discs, but it is not possible to play back still images and sound at the same time as with digital Δ-A discs. Koguiz: Because it is a Buddhist message, information transmission V) with a frequency band of several MHz is required.211
Information can be transmitted over a bandwidth of several tens of kilometres-1z in order to confirm the spread of information) and 11. Compared to digital audio discs that transmit “!”
This has the advantage that moving images can be played back together with audio signals. Therefore, in order to be able to properly reproduce the recorded information using jTX, it is desirable to interpret either the digital signal or the analog signal as '+TE' and record it depending on the information content.

Therefore, as mentioned above, the present applicant has created an information transmission@recording disk in which the analog 1:1 recording, the rack, and the digital recording track are respectively placed in d according to the information recording content. Regardless of the type of track from 1 to 1, it can be played properly without distinction, and 6 means the complete meaning of the above analog 1] G recording track and JR digital recording track. We have proposed an fjH for recording information signals and a device for producing information signals.

According to R, such a playback device can play back analog JIC recording 1-rack and digital recording 1-rack without distinguishing between people? 47, it has the excellent feature of maximizing the advantages of video discs and digital A-GerA discs.

J3, a detailed explanation of this information signal recording disc and its reproducing device is described in Japanese Patent Applications 1987-ε33232-ji to 1988-8ζ32ζ355, so the description thereof will be omitted.

Further, in FIG. 3, Δdr does not indicate the multiplexing position of one bit of the control bit Jτg used for random access or the like. This control signal distributes each pit data and transmits one bit in one processor. For example, all bits of Ruri-go-i-a are transmitted by a 19G block. (In other words, the control signal is composed of 196 bits.) Furthermore, U is called the user's bit "P4".
