ABSTRACT:
A disk unit has a function of loading a head on a disk from a holding mechanism during a load operation and unloading the head from the disk during an unload operation. The disk unit includes a controller which controls a movement of the head so that the loading operation and the unloading operation are carried out in a specific region on the disk, and the specific region extends for an angular range smaller than 360°. Alternatively, the controller controls the movement of the head so that the loading operation and the unloading operation are carried out uniformly in a circumferential direction of the disk within a specific region on the disk.
