Abstract:
1. An optical disc apparatus comprising: a disc rotation mechanism for placing and rotating a disc; a plurality of optical heads for emitting light beams for recording and/or reproducing data on the optical disc; a transport unit including a guide structure for guiding the optical heads to be radially transportable on the disc, an optical head transport mechanism for transporting the optical heads along the guide structure, and a transport base for supporting the disc rotation mechanism, the guide structure and the optical head transport mechanism; an optical head storing portion having a plurality of storage support guides for supporting and storing each of the plurality of optical heads; and an optical head insertion and removal mechanism for transporting each of the optical heads from the optical head storing portion to the transport unit or from the transport unit to the optical head storing portion, and wherein: each optical head stored in the optical head storing portion is transported to the transport unit by linearly moving from a position at which it is stored.
