Abstract
According to one embodiment, a magnetic disk device includes a disk, a write head, an adjustment unit, and a write processing unit. The adjustment unit adjusts each of a first adjustment value, a second adjustment value, and a third adjustment value. The write processing unit can select shingled magnetic recording and perform write processing based on the first to third adjustment values. When the number of the plurality of tracks of the band is t+1 and the number of unused sectors among the plurality of sectors of the band is e. The adjustment unit adjusts the first to third adjustment values to establish ext.

A magnetic disk device comprising:
- a disk including a band including a plurality of tracks, each of the tracks including a plurality of sectors;
- a write head writing data to the disk;
- an adjustment unit adjusting each of a first adjustment value that is the number of the plurality of sectors in each of the tracks of the band, a second adjustment value that is a length of each of the sectors in a circumferential direction of the disk, and a third adjustment value that is the number of the plurality of tracks of the band;
- and
- a write processing unit capable of selecting shingled magnetic recording processing of overwriting data to the plurality of tracks in a radial direction of the disk and performing write processing based on the first to third adjustment values,
- wherein
- when the number of the plurality of tracks of the band is t+1 and the number of unused sectors among the plurality of sectors of the band is e, the adjustment unit adjusts the first to third adjustment values to establish ext.
