ABSTRACT:
A microprocessor is provided for calculating, based on the target track address set in the target address register, the target velocity in the seek operation of the magnetic head up to the target track. When the target velocity of the magnetic head is comparatively large, the microprocessor increases the revision interval of the target velocity, based on a prestored program, such that it is larger than the normal revision interval. The microprocessor varies the target velocity revision interval by a pulse signal output from a circuit which divides the track pulse by 1/2, for example.
