Abstract
A magnetic disk device includes a disk including a plurality of areas divided in a radial direction, a head, and a controller configured to control the head to write data to a first area including a plurality of tracks that are separated from each other, and a second area including at least two adjacent tracks that partially overlap. A first distance between track centers of said two adjacent tracks in the radial direction is different from a second distance between track centers of another two adjacent tracks in the second area in the radial direction.
Claims20
A magnetic disk device, comprising:
- a disk including a plurality of areas divided in a radial direction;
- a head;
- and
- a controller configured to control the head to write data to a first area according to a normal recording format such that a plurality of tracks in the first area are separated from each other, and a second area according to a modified shingled recording format such that at least two adjacent tracks in the second area partially overlap, wherein
- a first distance between track centers of said two adjacent tracks in the radial direction is different from a second distance between track centers of a first track in the second area that is at one end of the second area in the radial direction and a second track in the second area that is adjacent to the first track in the radial direction.
A method for writing data to a magnetic disk, the method comprising:
- writing data to a first area of the magnetic disk according to a normal recording format such that a plurality of tracks are separated from each other;
- writing data to a second area of the magnetic disk according to a modified shingled recording format such that at least two adjacent tracks partially overlap, wherein
- a first distance between track centers of said two adjacent tracks in the radial direction is different from a second distance between track centers of a first track in the second area that is at one end of the second area in the radial direction and a second track in the second area that is adjacent to the first track in the radial direction.
