Title:
【発明の名称】磁気ディスク装置のヘッド位置決め方式
Document Type and Number:
Japanese Patent JP2550446
Kind Code:
B2
Abstract:
A head is moved toward an IGB1 at high speed until the IGB1 is detected, and then the head is moved toward an IGB2 at low speed until the IGB2 is detected. After the IGB2 is detected, a gradually increasing inverted drive current is fed to a VCM moving the head until an inversion of a direction of movement of the head is detected. After the IGB1 is not detected, a position control of the head is performed to position the head on a reference track. Rapid positioning of the head is attained even though an external force acting on a head actuator carrying the head varies.
