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 9):
A dual stage actuated suspension for a disk drive, comprising:\n a beam portion; a flexure mounted to the beam, the flexure including a gimbal tongue and a head slider mounted to the gimbal tongue for writing data to, and reading data from, a moving data medium, the gimbal tongue being gimbaled on the flexure to allow the head slider to pitch and roll as the moving data medium moves underneath the head slider; first and second shear-mode piezoelectric devices flexibly mounted to the flexure such that said first and second shear-mode piezoelectric devices have freedom of movement to move vertically without being rigidly coupled to each other in the vertical dimension; a mechanical coupling arranged so that activation of the first piezoelectric device causes a pushing force to be exerted on a first side of the gimbal tongue at the same time that activation of the second piezoelectric devices causers a pulling force to be exerted on a second side of the gimbal tongue opposite the first side, the simultaneous pushing and pulling forces on the gimbal tongue causing the gimbal tongue to rotate.
