Patent ID: 7006332

Claim:
A disk drive comprising: a magnetic recording disk having a surface containing a plurality of tracks for recording/reproduction of information; a voice coil motor; an arm responsive to the voice coil moor for placing the arm in operable relation to the surface of the disk; a coarse actuator capable of positioning the arm roughly to a predetermined track through oscillation of the arm; a load beam carried by the arm; a stator carried by the load beam; a gimbal carried by the load beam by means of metallic micro-beams; a magnetic head slider carried by the gimbal; a magnetic head carried by the magnetic head slider; and a rotor carried by the load beam; whereby said rotor and said magnetic head slider can be oscillated parallel to the surface of the magnetic recording disk, independently of the positioning of the coarse actuator when the coarse actuator positions the arm and the magnetic head slider roughly to a predetermined track through oscillation of the arm.
