Abstract
According to one embodiment, a disk device includes a disk-shaped recording medium, a magnetic head including a write head, a read head, and a heater, and a controller including a reference signal generator outputting a reference signal having a constant voltage amplitude at the same frequency as a high-frequency component of a gap measurement signal recorded in the recording medium, a measurer measuring a component amplitude of a reproduced signal of the gap measurement signal and an amplitude of the reference signal, and a heater controller controlling a power value of heater power supplied to the heater based on the measured values of the component amplitude and the amplitude of the reference signal.
