METHOD OF ADAPTIVELY CONTROLLING FLYING HEIGHT OF MAGNETIC HEAD, COMPUTER READABLE RECORDING MEDIUM RECORDING PROGRAM FOR EXECUTING THE METHOD BY COMPUTER, AND DISK DRIVE APPARATUS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method of adaptively controlling a flying height of a magnetic head, capable of determining FOP power by obtaining each flying height profile in accordance with a change in FOP power for each disk drive according to the operation temperature of a user environment, and to provide a disk drive apparatus using the same.;SOLUTION: The method of adaptively controlling a flying height of a magnetic head includes steps of: determining if parameter reset condition related to the flying height of the magnetic head has been set; measuring a temperature of a disk drive if the parameter reset condition has been set; obtaining a flying height profile of the magnetic head representing a variation of spacing between the magnetic head and a disk according to a variation of power supplied to a heater controlling the flying height of the magnetic head at the measured temperature; and determining power to be supplied to the heater corresponding to a target flying height of the magnetic head from the obtained flying height profile of the magnetic head.;COPYRIGHT: (C)2009,JPO&INPIT
