Abstract
According to one embodiment, there is provided a disk device including a head, a disk medium and a controller. The disk medium includes multiple zones concentrically provided. The controller, when two servo patterns corresponding to two adjacent zones are written by the head on a track of a boundary area between the two adjacent zones of the multiple zones, generates timing correction data according to a radial position of the boundary area. The controller writes one servo pattern of the two servo patterns on the track of the boundary area. The controller writes the other servo pattern of the two servo patterns, at a position circumferentially shifted from the one servo pattern in the track of the boundary area, according to the timing correction data.
