Abstract
A disk device includes a magnetic disk having a data non-recording region, and a data recording region inside the data non-recording region, a plurality of heads configured to read and write information from and onto the magnetic disk, and a plurality of arms supporting the heads, the arms being rotatable to move the heads from a parked position to a desired data recording position above or below the magnetic disk. Each of the arms comprises an overlapping region that overlaps the data recording region of the magnetic disk in a thickness direction of the magnetic disk when the heads are at the parked position.

A disk device comprising:
- a magnetic disk having a data non-recording region, and a data recording region inside the data non-recording region;
- a plurality of heads configured to read and write information from and onto the magnetic disk;
- and
- a plurality of arms supporting the heads, the arms being rotatable to move the heads from a parked position to a desired data recording position above or below the magnetic disk,
- wherein each of the arms comprises an overlapping region that overlaps the data recording region of the magnetic disk in a thickness direction of the magnetic disk when the heads are at the parked position.
A disk device comprising:
- a magnetic disk having a data non-recording region, and a data recording region inside the data non-recording region;
- a plurality of heads configured to read and write information from and onto the magnetic disk;
- and
- a plurality of arms supporting the heads, the arms being rotatable to move the heads from a parked position to a desired data recording position above or below the magnetic disk,
- wherein each of the arms comprises an overlapping region that overlaps the magnetic disk in a thickness direction of the magnetic disk when the heads are at the parked position, the overlapping region being divided into first and second areas of different thicknesses by a wall that connects a surface of the first area and a surface of the second area.
A disk device comprising:
- a first magnetic disk having a data non-recording region, and a data recording region inside the data non-recording region;
- a second magnetic disk having a data non-recording region, and a data recording region inside the data non-recording region;
- a first head configured to read and write information from and onto the first magnetic disk;
- a second head configured to read and write information from and onto the second magnetic disk;
- and
- an arm supporting the first and second heads at a first end of the arm, the arms being rotatable about a second end of the arm to move the first and second heads from a parked position to a desired data recording position above or below the first and second magnetic disks,
- wherein the arm has a first region between the first and second ends of the arm, that overlaps the data recording region of the first and second magnetic disks in a thickness direction of the magnetic disk when the first and second heads are at the parked position, and a thickness of a second region of the arm between the first and second ends of the arm is larger than a thickness of the first region of the arm.
