Abstract
According to one embodiment, a magnetic disk device includes a disk, a head that writes data to the disk and reads data from the disk, and a controller that obtains a gain to be changed according to a first value calculated based on first position information of the head and second position information of the head when writing a first track to the disk, calculates third position information of the head calculated based on the gain and the second position information, and writes a second track adjacent to the first track in a radial direction according to the third position information.
Claims20
A magnetic disk device comprising:
- a disk;
- a head that writes data to the disk and reads data from the disk;
- and
- a controller that obtains a gain to be changed according to a first value calculated based on first position information of the head and second position information of the head when writing a first track to the disk, calculates third position information of the head calculated based on the gain and the second position information, and writes a second track adjacent to the first track in a radial direction according to the third position information.
A write processing method that is applied to a magnetic disk device comprising a disk and a head that writes data to the disk and reads data from the disk, the write processing method comprising:
- obtaining a gain to be changed according to a first value calculated based on first position information of the head and second position information of the head when writing a first track to the disk;
- calculating third position information of the head calculated based on the gain and the second position information;
- and
- writing a second track adjacent to the first track in a radial direction according to the third position information.
