ABSTRACT:
A control device demodulates servo information read from a storage medium of a storage device via a head. A velocity demodulating unit demodulates a moving velocity of the head based on the servo information. A velocity correcting unit corrects the moving velocity, when an amount of change in demodulated moving velocity exceeds a predetermined threshold.
