Abstract

PURPOSE:To complete the reading of arrangement information about data with one-time operation and to output a data reading instruction from a controller to any disk by recording the data of the first disk and arrangement information about the data of the first to the N-th (N: an integer >=2) disks into the first disk. CONSTITUTION:When two disks are used, while the first data 3 and arrangement information 5 about the first data 3 and the second data 4 are recorded in the first disk 1, the second data 4 and arrangement information 6 about the first data 3 and the second data 4 are recorded in the second disk 2. When these two disks are simultaneously reproduced, while the first disk 1 is inserted into a player 15 of a disk reproducing device, the second disk 2 is inserted into a player 16 of the disk reproducing device. The operations of these players 15 and 16 are controlled by one controller 17, and at the time of initializing the operation, the controller 17 reads either the arrangement information 5 or the arrangement information 6 about data from the first data 3 to the second data 4 from either the disk 1 or the disk 2, stores the read information in a recorder 18, and outputs the reading instruction based on the stored information.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a disc recording method and disc for recording video and music together with their arrangement information on compact discs, laser discs, and the like.

2. Description of the Related Art As shown in FIG. 2, conventional disks have data and data arrangement information indicating where on the disk the data is placed recorded on each disk.

A group of data is recorded across the first disk 11 and the second disk 12, and the first data arrangement information 9 on the first disk 11 is recorded on the first disk 11.
, the second data arrangement information 10 on the second disk 12
are recorded on the second disk 12, respectively. FIG. 3 shows a block diagram of a disc playback device that plays two discs simultaneously. The first disc 11 is inserted into the player 15, and the second disc 12 is inserted into the player 1θ. When reading the first data 7 on the first disk 11, the control device 17 reads the arrangement information 9 of the first data on the first disk 11, stores it in the storage device 18, and moves the pickup to the desired data position. and reads the first data 7 on the first disk 11. Next, when reading the second data 8 on the second disk 12, the control device 17 erases the arrangement information 9 of the first data on the first disk 11 previously stored in the storage device 18, and 2 disk 12
Reads the second data arrangement information 10 of the storage device 18
Then, the pickup accesses the target data position and reads the second data 8 on the second disk 12.

FIG. 4 is a diagram showing the operation of the pickup 21 of the disc playback device that plays back both sides of the disc 19. This disc reproducing device can reproduce both sides of a disc 19 by moving a pickup 21, and can reproduce both sides of the disc 19 without turning the disc 19 over. The data arrangement information on the surface of the disk 19 is shown on the surface of the disk 19.
The arrangement information of the data on the back side of disk 19 is on the back side of disk 19.
Each is recorded. Therefore, in order to read the data on the front side of the disc 19, it is necessary to read the arrangement information recorded on the front side in advance, and in order to read the data on the back side of the disc 19, the arrangement information recorded on the back side must be read in advance. It had to be loaded in advance.

Problems to be Solved by the Invention In such a conventional configuration, it is necessary to read the data arrangement information recorded on the disc every time the disc to be played or the side of the disc to be played changes. It took me a long time to read it.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a disk recording method that allows target data to be read immediately even if the disk is replaced.

Means for Solving the Problems In order to solve the above problems, the present invention provides first data and arrangement information from the first data to the Nth data (N is an integer of 2 or more) on the first disk. , the second data and the arrangement information from the first data to the Nth data are stored on the second disk, and the third data and the arrangement information from the first data to the Nth data are stored on the third disk. , φ..., Nth data and arrangement information from the first data to the Nth data are recorded on the Nth disk.

Operation According to the present invention, with the above-described configuration, reading of data arrangement information can be completed in one time, and data reading commands can be issued from the control device to any disk.

Embodiment FIG. 1 is a diagram showing the recorded contents of two discs recorded by the recording method of the present invention, in which the first data 3, the first data 3, and the second data 4 are recorded on the first disc 1. The arrangement information 5 of
and the arrangement information 6 of the second data 4 are recorded. FIG. 3 shows a block diagram of a disc playback device that plays two discs simultaneously. The first disc 1 is inserted into the player 15 and the second disc 2 is inserted into the player 16.

The operations of the players 15 and 16 are controlled by one control device 17. During the initial setting of the operation, the control device 17
Arrangement information 5 or θ from the first data 3 to the second data 4 from the first disk 1 or the second disk 2
is read and stored in the storage device 18. The control device 17 stores the first data 3 and the second data 4 recorded on the first disk 1 based on the arrangement information 5 or 6 of the first data 3 and the second data 4 stored in the storage device 18. The second data 4 recorded on the disc 2 can be randomly accessed and desired data can be read.

FIG. 4 is a diagram showing the operation of the pickup 21 of the disc playback device that plays back both sides of the disc 19. The front side of the disk 19 has the first data and the arrangement information of the first to second data, and the back side has the second data and the first to second data.
Data arrangement information up to this point is recorded. The pickup 21 moves along the pickup slider 20,
Signals recorded on the front and back sides of the disc 19 can be taken out without turning the disc 19 over. At the beginning of the playback operation, after reading the arrangement information of the first to second data recorded in the lead-in area of the disc 19, the first data on the front side of the disc 19 and the second data on the back side are read. It can be accessed randomly and read desired data.

Data placement information is information that indicates where the data is placed on the disc, and includes information such as the start address of the track, the first track number, the last track number, and the start address of the lead-out area. . This location information is recorded in the lead-in area of the disc, and is read during initialization, allowing the pickup to access the target data based on this information.

Effects of the Invention As described above, the present invention has a first disk on a first disk.
data and the Nth data from the first data (N is an integer greater than or equal to 2)
The second disk contains the second data and the first data to the Nth data, and the third disk contains the third data and the first data to the Nth data. Since the arrangement information from the first data to the Nth data is recorded on the φ number disk, the Nth data and the arrangement information from the first data to the Nth data are recorded on the Nth disk. By reading the arrangement information of any of the disks up to the Nth disk once, the data from the first disk to the Nth disk can be accessed and read in a short time.
