ABSTRACT:
First and second disc drives which respectively read first and second discs on which signals are digitally recorded perform multiprocessing of each disc's signals by a single demodulator circuit based on commands from a host device. In this way, the single demodulator circuit is shared by the first and the second disc drives, and each disc drive can be used in the same way as two independent disc drives.
