Abstract
According to one embodiment, a magnetic disk device includes a circular magnetic disk on which a plurality of tracks for recording data are formed in a radial direction, and a magnetic head which can move in a radial direction of the magnetic disk and perform data write and read on each of the tracks of the magnetic disk. The tracks include pairs of two tracks adjacent to each other without a gap, each two being as a pair of tracks, and there are gaps respectively between these pairs of tracks.

A magnetic disk device comprising:
- a circular magnetic disk on which a plurality of tracks for recording data are formed in a radial direction;
- and
- a magnetic head which can move in a radial direction of the magnetic disk and perform data write and read on each of the tracks of the magnetic disk,
- wherein
- the tracks include pairs of two tracks adjacent to each other without a gap, each two being as a pair of tracks, and
- there are gaps respectively between these pairs of tracks.
A method of controlling a magnet disk device comprising:
- a circular magnetic disk on which a plurality of tracks for recording data are formed in a radial direction;
- and
- a magnetic head which can move in a radial direction of the magnetic disk and perform data write and read on each of the tracks of the magnetic disk;
- the tracks including pairs of two tracks adjacent to each other without a gap, each two being as a pair of tracks, and
- there being gaps respectively between these pairs of tracks,
- the method comprising:
- when the data written to one of the each pair of tracks overruns by a distance of a threshold value or more from the one of the tracks towards the other track side of the pair of tracks, rewriting the data written on the one track to the same one of the tracks, and rewriting the data written to the other track to the same other of the tracks.
