The slow access speed of the optical disk device has been further reduced. In addition, when there are a large number of optical discs, in order to search for an optical disc on which desired information is recorded from among the optical discs, it is necessary to set a large number of optical discs one by one in an optical disc device and search them out. , The search took a long time.

[0004] In order to cope with such a problem, an optical disk device provided with a recording device that stores the table of contents information and auxiliary information in the auxiliary information recording portion 110 on the optical disk device side,
A technology has been devised in which a recording element such as a semiconductor memory is mounted on an optical disk cartridge for accommodating an optical disk so that these recording devices and recording elements can be directly accessed to increase the access speed (Japanese Patent Application Laid-Open No. Sho.
An optical disk described in JP-A-2-128084).

The following problems arise in the above-mentioned prior art. First, in an optical disk device having a recording device that stores the table of contents information and auxiliary information of the auxiliary information recording portion on the optical disk device side, only the optical disk related to the table of contents information and auxiliary information stored in the recording device can be used. Poor in versatility. Next, in a technology in which a recording element such as a semiconductor memory is mounted on an optical disk cartridge for storing an optical disk, images and audio information are also recorded on the optical disk. It is difficult to store auxiliary information or the like corresponding to such a large amount of information in a recording element such as a semiconductor memory.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and provides an optical disk cartridge and an optical disk apparatus capable of increasing an access speed, shortening a search time and increasing a capacity of auxiliary information.
