Abstract

PURPOSE:To indicate the relation between sets of information recorded by a disk information forming person by recording address information of a relevant track and address information of other track corresponding to the relevant track onto a sub-code area as an auxiliary data. CONSTITUTION:Address information 14 of a main data 12 of the N-th track and address information 14 of a main data 12 of the M-th track are stored on an auxiliary data area of the N-th track and the address information 14 of the main data 12 of the M-th track and the address information 14 of the main data 12 of the N-th track are stored on an auxiliary data area of the M-th track, where M,N are integers. Since the auxiliary data area of the N-th track is referenced and the address of the M-th track relating to the N-th track is known even on the way of the reproduction of the N-th track, the M-th track is reproduced instantly as required.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a music area (hereinafter referred to as audio part) mainly for recording and playing back music, such as a compact disc video (hereinafter referred to as CDV), and The present invention relates to an information recording disc in which a video area (hereinafter referred to as a video part) for simultaneously recording and reproducing a moving image and music is recorded together with auxiliary information (hereinafter referred to as a subcode).

BACKGROUND OF THE INVENTION In recent years, information recording disc playback devices, typically compact disc players, that play back information recording discs on which digital audio data and auxiliary data have been recorded have been developed.
It is often used in combination with video equipment such as televisions, video disks, and video tape recorders, and information equipment such as personal computers and microcomputers, and there is a strong desire to handle not only audio but also images and data at the same time. For this reason, information recording disks that can handle various forms of information such as images, audio, and data in a composite manner have appeared.

Hereinafter, as an example of the conventional information recording disk mentioned above, C.
I) Explain V. A CDV is divided into two areas, an audio part and a video part, on the inner and outer peripheries, and the audio part contains digital data, similar to CDs (compact discs) and CD-ROMs (compact disc read-only memory). A digital data string consisting of audio data and auxiliary data is recorded, and in the video part, a signal obtained by FM modulating a composite video signal and the digital data string are frequency-divided and recorded, similar to a laser disc.

When a CDV playback device plays a CDV, the audio part outputs only an audio signal using digital audio data, and the video part outputs a composite video signal and audio using an FM modulated signal of the composite video signal and the digital audio data. Output a signal.

Problem to be Solved by the Invention However, in the above configuration, for example, in order to play back the first track of the audio part → the first track of the video part → the second track of the audio part, it is necessary to control the playback device at the time of playback. Therefore, there is no choice but to play each track in a pre-specified order, and depending on the intention of the disc producer, the order such as audio part 1 track → video part 1 track → audio part 2 track can be set as shown above. The problem was that it was not possible.

In view of the problem described in item 1, the present invention provides an information recording disc that records the addresses of other tracks related to auxiliary data and clearly shows the relationship between the recorded information of the disc producer and the information. .

Means for Solving the Problems In order to solve the second problem, the information recording disc of the present invention is an information recording disc consisting of a main data area and an auxiliary data area divided into a plurality of tracks, and the Nth track ( Address information of the main data of the N-th track and address information of the main data of the M-th track (M is an integer of 1 or more) are recorded in the auxiliary data area of the M-th track (N is an integer of 1 or more). Address information of the main data of the M-th track and address information of the main data of the N-th track are recorded in the auxiliary data area.

Effect: With the above-described configuration, the present invention allows the address of the M-th track related to the N-th track to be known by referring to the auxiliary data area of the N-th track even in the middle of reproducing the N-th track. Accordingly, the Mth track can be immediately played back.

Embodiment Hereinafter, an information recording disk according to an embodiment of the present invention will be described with reference to the drawings.

Figure 1(a) is a conceptual diagram of the audio part, video part, and auxiliary data on a CDv disc.
In a), the vertical axis is time.

Audio part 10 of main data + 2 shown in this conceptual diagram
Tracks 15 to 18 include songs 1 to 4.
Four types of digital audio data including songs are recorded, and four types of images, video 1 to video 4, are recorded in tracks 19 to 22 of video part 11. As shown in the correspondence table in Figure 1(b), the first song corresponds to video 1, and the second song corresponds to video 2.
The third song corresponds to video 3, and the fourth song records data corresponding to video 4. Auxiliary data I
3, as shown in FIG. 1(a), in the auxiliary data 13 of the audio part track 15, address a of the audio part track 15 and address e of the video part track 19 are recorded. In the auxiliary data of track I6, address b of track 16 of the audio part and address f of track 20 of the video part are recorded, and in the auxiliary data of track 17 of the audio part, the address of track 17 of the audio part is recorded. C and video part track 2
Address d of track 18 of the audio part and track 22 of the video part are recorded in the auxiliary data of track 18 of the audio part.
address h is recorded. The auxiliary data for track +9 of the video part contains the address of track 19 of the video part and track 15 of the audio part.
address a is recorded in the auxiliary data of track 20 of the video part.
address f and address b of track 16 of the audio part are recorded, and track 2I of the video part is recorded.
The auxiliary data includes address g of track 2■ of the video part and address C of track I7 of the audio part.
is recorded, and the auxiliary data of track 22 of the video part contains the address h of track 22 of the video part.
and address d of track 18 of the audio part are recorded.

As described above, according to this embodiment, if the address information of the corresponding track and the address information of another track corresponding to the corresponding track are recorded in the subcode area as auxiliary data, the auxiliary data can be auxiliary even when the corresponding track is played back. You can refer to the data and instantly move to the corresponding track.

Effects of the Invention As described above, the information recording disk of the present invention is an information recording disk consisting of a main data area and an auxiliary data area divided into a plurality of tracks, and the auxiliary data area of the Nth track (N is an integer of 1 or more). The address information of the main data of the Nth track and the address information of the main data of the Nth track (M is an integer of 1 or more) are recorded in the data area, and the address information of the main data of the Nth track is recorded in the auxiliary data area of the Nth track. By recording the address information of the main data of the track and the address information of the main data of the Nth track, the auxiliary data area of the Nth track can be referenced even during playback of the Nth track.
Since the address of the Nth track related to the Nth track can be known, the Nth track can be immediately reproduced if necessary. Therefore, for example, by associating a track with an audio part with a track with a video part in an auxiliary data area, mutual access can be made more quickly (not only is it easier to execute), but target addresses can be sequentially processed. Therefore, there is no need to have a storage device such as a correspondence table, and an information recording disk that can eliminate waste can be realized.
