Abstract
According to one embodiment, a magnetic disk device includes a disk, a head which writes data to the disk and reads data from the disk, and a controller which increases a first recording density of data to be written to a first sector having a first overwrite in the first sector and reduces a second recording density of data to be written to a second sector having a second overwrite different from the first overwrite, on a first track of the disk.

A magnetic disk device comprising:
- a disk;
- a head which writes data to the disk and reads data from the disk;
- and
- a controller which increases a first recording density of data to be written to a first sector having a first overwrite in the first sector and reduces a second recording density of data to be written to a second sector having a second overwrite different from the first overwrite, on a first track of the disk,
- wherein the first recording density and a third recording density of data to be written to a third sector which is adjacent to the first sector on the first track are different from each other.

A magnetic disk device comprising:
- a disk;
- a head which writes data to the disk and reads data from the disk;
- and
- a controller which increase a first recording capability of data to be written to a first sector having a first overwrite which is lower than a reference value in the first sector and reduces a second recording capability of data to be written to a second sector having a second overwrite which is higher than the reference value, on a first track of the disk,
- wherein the first recording capability and a third recording capability of data to be written to a third sector which is adjacent to the first sector on the first track are different from each other.
