Abstract

According to one embodiment, a magnetic disk device includes a disk including a servo sector including burst data, a head including a write head which writes data to the disk, and a read head which reads data from the disk, and a controller which generates a first normal servo gate for applying servo read to the servo sector, wherein when a short servo gate for at least applying servo read to the burst data is generated, the controller generates the short servo gate and the first normal servo gate, and when the short servo gate is not generated, the controller generates the first normal servo gate and a second normal servo gate different from the first normal servo gate.
