Abstract
A head suspension assembly couples a baseplate to a rotatable load through a planar triangular piezo microactuator for effecting hingeless rotation of the load. The microactuator expands, responsive to an excitation voltage, with greater magnitude in one direction than in another direction normal to the first direction, resulting in an angular movement of the hypotenuse thereby rotating the load. The upper surface of the microactuator is grounded to a bottom surface of the baseplate or load beam to position the microactuator lead connection surface closest to the load to facilitate trace routing. A load beam grounding surface may be raised to accommodate the microactuator and fix the lead connection surface on a common plane with the unraised surface to further minimize trace routing and provide access for bonding the trace to the load beam.
