In a conventional rewritable optical disk memory, for example, a disk is composed of only tracks recorded by a user as described in Japanese Patent Application No. 58-242006. However, in this disc as well, in order to divide tracks and record information in sector units, sector marks, sector addresses,
Read-only information such as a clock is provided. However, the provision of a read-only track other than the sector header information was not considered.

By the way, in a magnetic disk memory for a personal computer which has been put into practical use, two drive devices are usually used, one of which is used as a maker-supplied program such as an operating system, and the other is used as a memory for a user-recorded data and program. . Considering the application of a rewritable optical disk to a personal computer memory as a high-density, large-capacity memory with a recording density about 100 times that of the current magnetic record carrier, a large-capacity optical disk, a replay of read-only information. It is desirable to have an information structure on a disc that makes use of features such as large-scale duplication by means of, and simultaneous reproduction of concavo-convex phase information and magneto-optical information.

An embodiment of the present invention will be described below with reference to FIG. First
The figure shows the information recording surface of the optical disc, where 1 is a track area where a user records data, 2 is a sector header, and 3 is a read-only track area. Like 3, the information is given in the form of concave-convex pits that have been optically recorded in advance, so that 3 can be mass copied by replication. A program such as an operating system can be preliminarily put in the portion 3 and one optical disk as shown in FIG. 1 and one driving device, two magnetic floppy disks for the current personal computer, and the driving device 2 can be used. And the recording capacity is 100 times to 1,0
It will be 00 times.

According to the present invention, as shown in FIG. 2, some reproduction-only track portions are divided and arranged on the disc surface, and several different operating systems are stored in one optical disc. It is also applied to the shape of recording the user data handled in (3) in the user data track portion adjacent to each operating system. By doing so, access can be made faster and data management can be performed more than the format in which several operating systems are stored in one ROM track part.
It will be clear for each operating system.
