ABSTRACT:
A rotating motor control apparatus for a recordable optical disk unit is constructed to include a data synchronizing rotation control circuit controlling rotation of a rotating motor in synchronism with a recorded data signal, a zigzag synchronizing rotation control circuit controlling the rotation of the rotating motor in synchronism with a zigzag of a guide groove of a disk, a phase synchronizing circuit synchronizing to a phase of the data signal, and a synchronous detection circuit detecting a synchronized state of the phase synchronizing circuit and outputting a lock signal, where the data synchronizing rotation control circuit drives the rotating motor when the lock signal is obtained, and the zigzag synchronizing rotation control circuit drives the rotating motor when no lock signal is obtained.
