Patent ID: 6898042

Claim:
A data storage device comprising: rotatable storage medium for storing data along concentric tracks on a surface of the medium; a transducer supported by a slider to transfer data between the transducer and the medium; and an actuator assembly supporting the slider adjacent the medium at a fly height from the surface of the medium, the actuator assembly comprising an actuator arm, a suspension supported by the actuator arm, a microactuator coupling the slider to the suspension, and an actuator for moving the actuator arm to thereby move the transducer across tracks on the storage medium, the microactuator comprising: a rotor supporting the slider, a stator supported by the suspension, at least one magnet supported by one of the rotor or stator, first and second coils supported by the other of the rotor or stator, the first coil being operatively coupled to at least one magnet so that current in the first coil alters magnetic flux linkage with at least one magnet to move the rotor in a direction across tracks on the storage medium, and the second coil being operatively coupled to at least one magnet so that current in the second coil alters magnetic flux linkage with at least one magnet to move the rotor to adjust the fly height.
