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 13):
A dual stage actuated suspension for a disk drive, comprising:\n a beam; a flexure mounted to the beam, the flexure including a gimbal tongue and a head slider mounted thereto 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; a shear-mode piezoelectric device mounted to the flexure; and a flexible connector extending from the shear-mode piezoelectric device to the gimbal tongue; wherein when the piezoelectric device is actuated:\n the shear-mode piezoelectric device moves the flexible connector in a first longitudinal direction; and \n the movement of the flexible connector causes the head slider to rotate.
