Abstract
A method (and apparatus) for operating a disk drive apparatus. The method includes moving a movable member about a fixed position to move a read/write head coupled to a slider to a selected track on a disk. The selected track is at least one of a plurality of tracks. The method includes adjusting a position of the read/write head using an actuating device integrated on the gimbal. The actuating step moves the read/write head relative in a manner normal to the track on the magnetic disk to align the read/write head on the track using a finer and faster alignment of the read/write head than the moveable support member.
