摘要：
According to one embodiment, a disk has a set of tracks thereon. A controller performs refresh control for reading data by a head from a track on the disk to be refreshed and for writing the read data by the head to a spare track adjacent to the track from which the data has been read. The controller switches the track from which the data has been read to a new spare track after the writing.
