Abstract:
A PZT microactuator such as for a hard disk drive has a restraining layer bonded on its side that is opposite the side on which the PZT is mounted. The restraining layer comprises a stiff and resilient material such as stainless steel. The restraining layer can cover most or all of the top of the PZT, with an electrical connection being made to the PZT where it is not covered by the restraining layer. The restraining layer reduces bending of the PZT as mounted and hence increases effective stroke length, or reverses the sign of the bending which increases the effective stroke length of the PZT even further. The restraining layer can be one or more active layers of PZT material that act in the opposite direction as the main PZT layer. The restraining layer(s) may be thinner than the main PZT layer.

Claim (Index 12):
The microactuator assembly of  claim 11  wherein when the microactuator activation voltage is applied to the microactuator assembly, the microactuator assembly acts in the direction of the first piezoelectric layer a greater overall distance than if the plurality of restraining piezoelectric layers were not present.
