Abstract
According to an embodiment, upon a failure in detection of a servo mark from servo data recorded in a first normal servo sector in a write operation, a controller of a magnetic disk device stops a write operation. Then, the controller demodulates the servo data including the servo mark, for the servo data recorded in a first short servo sector being a short servo sector immediately before the first normal servo sector, and resumes the write operation from a data area immediately after the first normal servo sector.
