Patent ID: 8730771

Claim:
A recording/reproducing device that records information onto and reproduces information from a double-sided information recording disk, the information recording disk having a first side and a second side, the first side and the second side corresponding respectively to an upper surface and an lower surface or vice versa, the recording/reproducing device comprising: a first recording/reproducing unit which records information onto the first side of the information recording disk and/or reproduces information therefrom; a second recording/reproducing unit which records information onto the second side of the information recording disk and/or reproduces information therefrom; a disk storage unit which stores the information recording disk; a first conveyor unit which conveys the information recording disk between the disk storage unit and the first recording/reproducing unit; a second conveyor unit which conveys the information recording disk between the disk storage unit and the second recording/reproducing unit; and a control unit which controls each of the units; wherein, while the first recording/reproducing unit or the second recording/reproducing unit is performing a data recording process on the first side or the second side of the information recording disk, the control unit interrupts the data recording process, causes the first conveyor unit or the second conveyor unit to convey the information recording disk to a recording/reproducing unit different from the recording/reproducing unit currently engaged in the data recording process, and allows the different recording/reproducing unit to perform a data reproducing process on data recorded on a side different from the side of the information recording disk on which the data recording process was performed.
