Patent ID: 8169750

Claim:
A test cartridge, comprising: A, a head mounting block, wherein the head mounting block has a gimbal support surface for a magnetic head gimbal assembly to be mounted for read or write testing; B, a cartridge base having a planar actuator support surface on one side thereof; C, a piezo actuator affixed to the actuator support surface, wherein the piezo actuator includes a drive end which is able to move along a displacement axis in response to an applied signal, and wherein the displacement axis is parallel to the actuator support surface of the cartridge base, and D, a blade flexure, wherein the blade flexure includes (i) a first end rigidly attached to the cartridge base along a first axis parallel to the actuator support surface and perpendicular to the displacement axis, and (ii) a second end rigidly attached to the head mounting block along a second axis substantially parallel to the first axis, wherein the blade flexure is relatively long in a direction extending between the first end and the second end and is relatively short in a direction transverse thereto, and whereby the mounting block is disposed along the displacement axis and is in communication with the drive end of the piezo actuator, and whereby the drive end of the piezo actuator is able to move the head mounting block and the gimbal support surface in the direction of the displacement axis in response to an applied signal while maintaining the first axis and the second axis to be substantially parallel.
