METHOD OF REDUCING ABRASION OF DISK BY USING DITHERING PROCESS AND DISK DRIVE USING THE SAME

摘要

Embodiments of the invention reduce abrasion of a disk via a dithering process that spreads a friction area between a magnetic head and the disk when a magnetic head lifts from the surface of the disk. In embodiments of the invention, the dithering process is executed only when the magnetic head is latched in a parking zone of the disk and when a disk spindle motor is in an acceleration mode.
