ABSTRACT:
An optical disk apparatus for controlling two optical pickups in an optimized way in response to operation modes for rotating the optical disk. When receiving a request for seeking one optical pickup from a HOST, a CPU judges whether to move the other optical pickup synchronously to satisfy positional restriction of the two optical pickups. Furthermore, when operating one optical pickup upon, for example, a read request. from the HOST, the CPU judges whether to move the other pickup to follow.
