METHOD FOR WRITING REFERENCE SERVO SIGNAL IN HARD DISK DRIVE AND METHOD FOR COMPENSATING FOR TEMPERATURE

摘要

PROBLEM TO BE SOLVED: To provide a method for writing a reference servo signal in a hard disk drive and a method for compensating for temperature.;SOLUTION: This method for recording a reference servo signal includes the steps for writing a first reference pattern in an end direction of a reference servo signal writing concentrically on the disk; writing a reference servo signal on a current spiral track from a reference writing start position of the current spiral track; detecting a moving angle of an actuator arm to the first reference pattern, which corresponds to a distance from the writing start position to a reference writing end position in the case that thermal expansion of the disk does not exist; compensating for a driving speed of the actuator arm with reference to the detected moving angle; and writing the reference servo signal on a next spiral track at a compensated driving speed of the actuator arm.;COPYRIGHT: (C)2006,JPO&NCIPI
