Abstract:
1. A disk drive comprising: a slider that flies over a rotating recording disk; a head element section that is mounted on the slider; a heater that is mounted on the slider to protrude the head element section by means of thermal expansion for the purpose of adjusting the clearance between the head element section and the recording disk, wherein the heater is a thin film resistive element located above a write element and a read element in a height direction relative to the recording disk, and located between the write element and the read element in a direction along a surface of the recording disk; an actuator that retains and moves the slider; an acceleration detection section; and a controller for controlling the heater in accordance with the acceleration detected by the acceleration detection section, wherein the controller turns OFF the heater when the acceleration detection section detects an acceleration lower than a first reference level in the direction of gravity.
