Abstract
Embodiments of the present invention help to effectively remove adhesion on a head slider. In an embodiment of the present invention, a hard disk controller/multiprocessing unit (HDC/MPU) raises the temperature on the surface of a head slider with a heating element on the head slider to remove adhesion on the head slider while an actuator stays on a ramp. The HDC/MPU varies the amount of heat in accordance with the temperature sensed by a temperature sensor. This achieves removal of the adhesion on the head slider, maintaining reliability.
