Patent ID: 8898684

Claim:
An optical disc device comprising: optical disc drives each having a tray conveyed between a recording and reproducing position and a disc replacing position through a tray discharge port formed in one surface of a casing, the optical disc drives performing at least either recording or reproduction with respect to an optical disc mounted on the tray positioned at the recording and reproducing position; a carrier which holds a plurality of stacked optical discs in a stacked state, the carrier being configured to mount the held plurality of optical discs on each tray of the optical disc drives, the tray being positioned at the disc replacing position, and the carrier being configured to collect the plurality of optical discs mounted on each tray in the stacked state; a control unit which controls operations of the optical disc drives and the carrier, wherein the optical disc drives include: a first optical disc drive group having a plurality of disc drives stacked in a height direction such that tray discharge ports of the first optical disc drive group are oriented in one direction; and a second optical disc drive group having a plurality of disc drives stacked in the height direction such that tray discharge ports of the second optical group are opposed to the tray discharge ports of the first optical disc drive group, and wherein the control unit is configured to perform, in parallel: a first control operation to convey a first tray in the first optical disc drive group from the disc replacing position to the recording and reproducing position, and a second control operation to convey a second tray in the second optical disc drive group from the recording and reproducing position to the disc replacing position, the second tray being opposed to the first tray.
