ABSTRACT:
A disk drive is disclosed which performs a head positioning operation capable of coping with a variation of an offset caused by a disk runout. A CPU of a head positioning control system calculates a second position offset amount by correcting a first position offset amount corresponding to a rotation angle of an actuator on a disk medium based on a disk runout amount. The CPU performs head positioning control including a position correction operation corresponding to a second position offset amount.
