Most of the conventional information disk recording / reproducing apparatuses perform recording / reproducing on a single disk, and a so-called bare state or a so-called naked state is provided at an installation portion of a pickup for performing recording / reproducing on the disk. It was transported and loaded according to the state of being stored in a caddy.

Further, since the information disk recording / reproducing apparatus is configured to handle one disk, when processing is performed on a plurality of disks, for example, the contents of an encyclopedia (pictures and photographs including documents, etc.) And the like), and when recording large-capacity information such as images, it is necessary to exchange a complicated disk.

For this reason, an apparatus which stores a plurality of disks and automatically exchanges the disks has been devised. As a method of storing a plurality of disks in the apparatus, a plurality of disks that can be inserted and stored one by one from one insertion slot are stored in the apparatus, or a cartridge that stores a plurality of disks is used. There is a method of sequentially loading from the loaded cartridge. In particular, the latter method using a cartridge is frequently used because of its convenience such that the disc can be replaced at a time by exchanging the cartridge and the portability is excellent.

A plurality of audio CDs, such as those found in a multi-disc player for reproducing an audio CD in consideration of a form such as a vehicle, are loaded into a cartridge (magazine) and are sequentially selected for reproduction.
