  • Patent number: 7046486
    Abstract: A micro-flexure is provided for achieving secondary actuation in an actuator of a disk drive. The micro-flexure is a separate element which attaches to a standard flexure. A slider mounts to the micro-flexure. Piezoelectric elements attach to the micro-flexure to provide the motive force for displacing the micro-flexure during secondary actuation. The secondary actuation is thereby achieved by isolating movement at the slider.
    Type: Grant

  • Patent number: 5355267
    Abstract: A suspension for a read/write head of a disk drive is fixed to a side wall of an arm. If two heads are to be suspended, a first suspension for one head and a second suspension for the other head are fixed to opposite side walls of the arm. Since the suspension is fixed to the side wall of the arm, there are no screw heads protruding or projections formed by hot staking on the top and the bottom surfaces of the arm and it is not necessary to make screw holes which extend from the top surface or the bottom surface into the arm perpendicularly to these surfaces. Thus, the vertical thickness of the head carriage assembly can be decreased.
