    摘要: 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.

    摘要: A microactuated disk drive suspension for supporting a slider at a disk includes a load beam extending in a plane and having on a common axis a base section adapted for mounting to an actuator, a spring section and a beam section carrying a flexure and the slider thereon. The suspension has relatively movable proximate and distal portions on the common axis that are joined by a bending system cantilevered from the proximate portion and including a cantilevered bending motor opposed to the common axis and having a laterally bendable unsupported region. A cantilevered laterally bendable load assist structure defined by the suspension edges is provided arranged to block undue loading of the bending motor unsupported region.

    摘要: A disk drive suspension and method has a limiter structure that limits movement of the tongue relative to a surrounding frame by extending the plastic film layer and optionally the metal layer components of a flexure-defining flexible circuit laminate beyond the flexure tongue distal end and attaching the terminal regions of the extended components to the surrounding frame laterally of the tongue. The flexure-defining laminate is attached to the suspension rigid portion proximally and optionally distally as well as laterally with the limiter structure. A lift tip can be used to enable lifting of the suspension and to stiffen the suspension in lieu of the distal attachment of the flexible circuit.
