Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk recording method and a disk for recording video and music, such as compact disks and laser disks, together with their arrangement information.

2. Description of the Related Art As shown in FIG. 2, in a conventional disk, data and data arrangement information indicating where the data is arranged on the disk are recorded on each of the disks. A group of data is recorded over the first disk 11 and the second disk 12, and the first disk
The first data arrangement information 9 of 11 is stored in the first disk 11
The arrangement information 10 of the second data of the second disk 12 is recorded on the second disk 12, respectively. FIG. 3 shows a block diagram of a disk reproducing apparatus for reproducing two disks simultaneously. Insert the first disc 11 into the player 15,
Insert the second disc 12 into the player 16. When reading the first data 7 of the first disk 11, the controller 17 stores the first data arrangement information 9 of the first disk 11 in the storage device 18 for reading, and picks up the target data position. To read the first data 7 of the first disk 11. Next, when reading the second data 8 of the second disk 12, the control device 17 erases the arrangement information 9 of the first data of the first disk 11 previously stored in the storage device 18, and 2
The second data arrangement information 10 of the second disk 12 is read and stored in the storage device 18, and the pickup accesses the target data position to read the second data 8 of the second disk 12.

FIG. 4 is a diagram showing the operation of the pickup 21 of the disc reproducing apparatus for reproducing both sides of the disc 19. A disc player that can play both sides of the disc 19 by moving the pickup 21.
Both sides can be played. The data arrangement information on the front surface of the disk 19 is recorded on the front surface of the disk 19, and the data arrangement information on the rear surface of the disk 19 is recorded on the back surface of the disk 19. Therefore, in order to read the data on the back surface of the disk 19, it is necessary to read the arrangement information recorded on the front surface in advance, and to read the data on the back surface of the disk 19, the arrangement information recorded on the back surface is read. It had to be read in advance.

In such a conventional configuration, every time the disc to be reproduced or the surface of the disc to be reproduced is changed, it is necessary to read the arrangement information of the data recorded on the disc,
It took a long time to read the target data.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a disk recording method capable of immediately reading target data even when a disk is replaced.

Means for Solving the Problems In order to solve the above problems, the present invention provides a first disk with first data and arrangement information from the first data to the Nth (N is an integer of 2 or more) data. On the second disk, the arrangement information from the second data and the first data to the Nth data, and on the third disk, the arrangement information from the third data and the first data to the Nth data. , ..., Nth
And N-th data and arrangement information from the first data to the N-th data.

Operation In the present invention, with the above-described configuration, the reading of the data arrangement information can be completed in one time, and the control device can issue a data reading instruction to any disk.

FIG. 1 is a diagram showing the recorded contents of two discs recorded by the recording method of the present invention, and the first disc has first data 3, first data 3, and second data 4 recorded on the first disc. Placement information 5
In the second disk 2, the arrangement information 6 of the second data 4, the first data 3, and the second data 4 is recorded. Third
The figure shows a block diagram of a disk reproducing apparatus for reproducing two disks 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 player 15 and the player 16 are controlled by one controller 17. The control device 17 reads the arrangement information 5 or 6 from the first data 3 to the second data 4 from the first disk 1 or the second disk 2 at the time of initial setting of the operation, and stores it in the storage device 18. . The control device 17 stores the arrangement information 5 of the first data 3 and the second data 4 stored in the storage device 18.
Or random access to the first data 3 recorded on the first disk 1 and the second data 4 recorded on the second disk 2 based on 6 to read desired data. Can be done.

FIG. 4 is a diagram showing the operation of the pickup 21 of the disc reproducing apparatus for reproducing both sides of the disc 19. Disc 19
On the front surface, the arrangement information of the first data and the first and second data is recorded, and on the back surface, the arrangement information of the second data and the first and second data are recorded. Pickup 21
Moves along the pickup slider 20 and the disc
Signals recorded on the front and back surfaces of the disk 19 can be taken out without turning over the disk 19. At the beginning of the reproducing operation, after reading the arrangement information of the first to second data recorded in the lead-in area of the disk 19, the first data on the front surface and the second data on the back surface of the disk 19 are read. Access can be made randomly and desired data can be read.

The data location information is information indicating where the data is located on the disc, and 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. There is. This arrangement information is recorded in the lead-in area of the disk, is read at the time of initialization, and causes the pickup to access target data based on this information.

As described above, according to the present invention, the first disk stores the first data and the arrangement information from the first data to the Nth data (N is an integer of 2 or more) on the second disk. Second
, And the third disk with the third data and the arrangement information from the first data to the Nth data,..., Nth data. Since the Nth data of the first disk and the arrangement information from the first data to the Nth data are recorded, the arrangement information of any one of the disks from the first disk to the Nth disk is set to 1
The data from the first disk to the Nth disk can be accessed and read in a short time only by reading the data a number of times.
