Abstract
According to one embodiment, a magnetic disk device comprises a head position demodulation unit which demodulates a position of the head by performing switching between normal servo demodulation for processing servo information written to a servo sector of the disk and short servo demodulation for processing servo information by a short servo system, and a controller comprises a head position prediction unit which predicts a head position, and the head position prediction unit performs position prediction by using a latest head position obtained by demodulation by the head position demodulation unit and a head position obtained by past demodulation by normal servo demodulation.
