Abstract
The method of the invention is performed on a disk drive with at least a rotatable disk and a head/arm mechanism movable thereover. The disk has a plurality of concentric tracks, including innermost and outermost tracks and an intermediate track positioned therebetween, with the intermediate track including often-used records. The method reduces movements of the head/arm mechanism through the steps of: positioning the head/arm mechanism over the intermediate track; moving the head/arm mechanism away from the intermediate track to another track to perform a requested read operation; moving the head/arm mechanism back to the intermediate track from the further track and performing write actions in the tracks over which the head/arm mechanism moves in its traversal back to the intermediate track.
