Abstract:
A dual stage actuated (DSA) suspension uses two shear-mode PZT microactuators to finely position the head slider. The bottom surfaces of the PZTs are affixed to the flexure, and the PZT top surfaces move forward and backward, respectively, in push-pull fashion when the PZTs are activated. Flexible connector arms attach the tops surfaces of the PZTs to the gimbal tongue such that activating the PZTs causes the gimbal tongue to rotate, with the connector arms acting as levers to magnify the motion such that a relatively small shear movement of the PZTs results in a significantly larger lateral movement of the head slider across the data disk.

Claim (Index 1):
A dual stage actuated suspension for a disk drive, comprising:\n a beam portion; a flexure mounted to the beam portion, the flexure including:\n first and second flexible outrigger arms extending on respective lateral sides of the flexure from a relatively fixed portion of the flexure; and \n a gimbal tongue; \n a head slider mounted to the gimbal tongue for writing data to, and reading data from, a moving data medium containing a plurality of data tracks thereon; a first shear-mode piezoelectric device mounted at a distal end of the first flexible outrigger arm, the first shear-mode piezoelectric device having a top surface, a bottom surface, and two electrodes, the top surface moving in a linear shear direction relative to the bottom surface when an actuation voltage is applied across the electrodes; and a mechanical coupling that, in response to the piezoelectric device being activated, couples the shear movement of the piezoelectric device to rotational movement of the head slider.
