ABSTRACT:
A disc changer is provided to support each of a plurality of bare discs for recording and/or regeneration on a separate disc rack board without requiring a cartridge. The disc rack boards are positioned so as to form a vertical stack. A carrier is provided which moves only in the vertical direction along the vertical stack of disc rack boards. Furthermore, a plurality of disc drives is provided in a vertical stack opposing the vertical stack of disc rack boards. A hand is provided which moves only in a direction perpendicular to the direction in which the carrier moves, and operates to transfer one of the plurality of bare discs between one of the plurality of disc rack boards and the carrier and between one of the plurality of disc drives and the carrier. Thus, the number of discs which may be loaded is increased while the size of the disc changer is minimized.
