Abstract
According to one embodiment, a disk drive includes a heating element which is provided on a head and generates heat when supplied with power, thereby to adjust a dynamic flying height of the head. A head-movement detecting unit detects the abnormal movement of the head, a value of which is larger than a preset movement value during a head positioning control. In this case, a heating-element controller stops supplying power to the heating element.
