Embodiment Construction

[0021] Hereinafter, embodiments of the present invention will be described using the drawings.

[0022] figure 1 It is an example schematic configuration diagram of an optical disc device of the present invention.

[0023] When the optical disc 4 is inserted into the optical disc slot 23 of the optical disc device 20, the optical disc 4 is sent to the optical disc drive 21, and information is recorded, reproduced, or erased. Furthermore, by operating a disc exchange switch or a remote control device to instruct disc exchange and disc storage, the optical disc 4 is ejected from the optical disc drive 21 and stored in the changer 22 . The switcher 22 stores multiple optical discs, and can send the optical disc 4 to the optical disc drive 21 or store the optical disc 4 sent out from the optical disc drive 21 . In addition, a structure in which the optical disk 4 is directly transferred between the optical disk entrance 23 and the switcher 22 may be used. In addition, by provid...
