摘要:
A drive system for use in an optical disk file device has a multipolar motor such as a three-phase linear DC motor for positionally controlling a read/write head and driving the same to track an optical disk. Selection of the coils of the motor and phase switching of the coils are stopped while the drive system is in the tracking mode.
