ABSTRACT:
A disc unit for recording or reproducing information on or from a recording/reproducing disc loaded therein, in which the disc, which is inserted into the disc unit through an insertion opening thereof is transferred to its operative position and the loaded disc is transferred from its operative position toward the insertion opening, through which the disc is discharged. The loaded disc is clamped at its operative position by the clamping mechanism. The single driving motor is selectively coupled to either one of the disc transfer mechanism or the clamping mechanism. The loaded disc can be discharged manually from the unit by controlling the rotating axis of the single driving motor from the outside of the unit. The insertion opening is shielded automatically when the loading is completed by the shielding plate. The plate may display a sign "LOADED". The recording/reproducing disc may be a magnetic disc or an optical disc.
