METHOD FOR RECORDING SERVO TRACK IN DYNAMIC HEAD LOADING DRIVE

摘要

PURPOSE: A method for recording a servo track in a dynamic head loading drive is provided to improve the accuracy of a position of a servo track by guaranteeing contact between a push pin and an actuator body during servo writing. CONSTITUTION: A head is moved to a home position on a disk. The head is pushed toward an OD(Outer Diameter) to be moved to an interference possible area with a loading ramp. A first ramp test is executed to confirm whether interference is sensed by a contact state between a push pin of a servo track writer and an actuator body. The ramp test is repeated while moving the head toward the OD or an ID(Inner Diameter) as many as preliminarily set track numbers to start fine adjustment according to the sensed result of the interference. The ramp test is repeated while moving the head toward the OD or the ID as many as preliminarily set track numbers to decide a servo track start point according to the sensed result of the interference.
