Abstract: A multiple disc changer apparatus has an elastic support mechanism for supporting the recording/reproducing unit on a main body of the apparatus and includes a locking mechanism for controlling the elastic support of the elastic support mechanism when a disc is loaded on the recording/reproducing unit by a chucking mechanism.

Abstract: An optical disc reproducing apparatus and an optical disc reproducing method are adapted to use, as a medium for reproduction, an optical disc on which audio signals are recorded to repeat such an operation to control a read-out system by a signal indicating loop reproduction to move read-out position of data to a position traced back in time by a predetermined number of tracks to carry out reproduction up to the position where execution of loop is started to move the read-out position to the position traced back therefrom. Thus, effects similar to the scratch rendition of the record disc of an analog system can be provided.

Abstract: A recording and/or reproducing apparatus for discs includes a housing unit housing a large number of discs, a recording and/or reproducing unit on which one of the discs held within a large number of disc holders provided in the housing unit is selectively loaded, and a transporting mechanism for transporting the disc held within a selected one of the holders of the housing unit to the recording and/or reproducing unit. The disc transporting mechanism detects whether or not the disc is held in the holder. A detection switch is activated when no disc is present in the holder. The housing unit includes a plurality of the holders positioned radially such that the disc surfaces are held upright. The selected disc held in the holder of the disc transporting mechanism is transported by the transporting mechanism in the upright position to the disc reproducing unit and loaded therein.

Abstract: A recording and/or reproducing apparatus for discs including a housing unit housing a large number of discs, a recording and/or reproducing unit on which one of the discs held within a large number of disc holders provided in the housing unit is selectively loaded and a transporting mechanism for transporting the disc held within a pre-set one of the holders of the housing unit to the recording and/or reproducing unit. In the course of transporting the disc, the disc transporting mechanism detects whether or not the disc is held in the holder. The housing unit include a plurality of the holders for radially holding the discs with the disc surfaces being erected upright. The disc held in the holder is transported by the transporting mechanism in the upstanding position as far as the disc reproducing unit and there loaded.
