Abstract
In a hard disk drive (HDD), a ratio of the distance R between the axis of rotation of an actuator and a magnetic head to the distance R0 between the axis of rotation of the actuator and the center of a disk is in the range of 0.9 to 0.96. Thus, the deviation of the skew angles for the tracks from 0 degrees is minimized and yet a swing arm of the actuator can be relatively short. Accordingly, not only is the recording density maximized, but the HDD can be small and light as well.
Claims4
A hard disk drive (HDD) comprising:
- a disk having a recording region containing a plurality of tracks each extending in the circumferential direction of the disk, the tracks being concentric with respect to a center of the disk;
- a magnetic head operative to read information from and/or record information on the recording region of the disk;
- and
- an actuator supported so as to be rotatable about an axis, the magnetic head being supported by the actuator so as to rotate therewith about said axis, and
- the ratio R/R0 of the HDD being in the range of 0.9 to 0.96 wherein R is the distance between the axis of rotation of the actuator and the magnetic head, and R0 is the distance between the axis of rotation of the actuator and the center of the disk.
