ABSTRACT:
A region of flexure layer, including slider mounting face coupled to offset mounting face for at least one piezoelectric device. The offset mounting face for piezoelectric device provides asymmetry between first contact region and second contact region. This is cost effective, reliable support for piezoelectric devices used for micro-actuation in hard disk drives. The slider moves based upon asymmetry of the offset mounting face coupled to the piezoelectric device twisting the slider mounting face. The invention includes flexure containing the region of the flexure layer. The invention includes head gimbal assembly including flexure, actuator arm including head gimbal assembly, and actuator assembly including actuator arm, and hard disk drive including actuator assembly. The invention includes manufacturing the region, the flexure, the head gimbal assembly, the actuator arm, the actuator assembly and the hard disk drive, as well as these products of the manufacturing processes.
