Abstract
According to one embodiment, a controller performs processing when a magnetic head passes over a servo region. The processing includes acquiring a first burst demodulated signal by demodulating a first burst pattern, and acquiring a second burst demodulated signal by demodulating a second burst pattern. The processing includes interpolating a first correction value for a first demodulation position based on first correction values acquired from a first radial position and a second radial position. The processing includes interpolating a second correction value for the first demodulation position based on second correction values acquired from the first radial position and the second radial position. The processing includes correcting amplitude of the first burst demodulated signal by using the first interpolation correction value, and correct amplitude of the second burst demodulated signal by using the second interpolation correction value.
