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 with a low profile limiter structure located within the vertical extent of the slider, the tongue free and any gap provided by the limiter structure so as to not increase the overall vertical extent of the suspension. The limiter structure has a tab separated on three sides from the suspension beam portion and extending from the beam portion locus toward the suspension tongue portion free end. The tab has a projecting shoulder spaced at a gap from the beam portion. The tongue free end outer terminus has an opening that interfits with the tab in tab shoulder engaging relation to block free end movement away from the locus beyond that permitted by the gap.

摘要： A multi-step shock limiter in a disk drive suspension assembly has a load beam and a flexure, with a plurality of limiting pairs. A first limiting pair has a clearance less than that of any other limiting pair, and is flexible. During a shock condition, vertical movement of the flexure with respect to the load beam causes the first limiting pair to engage and absorb shock. Further movement engages at least one additional pair, redistributing the shock thereamong until all pairs engage, thereby substantially anchoring the flexure to the load beam and limiting further movement of the flexure. The limiters may comprise a double tee shape having two legs and a cross member, with the first limiter defined by the cross member between the legs, and two additional limiters defined by the ends of the cross member that extend beyond the legs. The limiters engage corresponding tabs or tongues.

摘要： Shock performance and stiffness of hard disk drive lifters are enhanced by extending one or more portions of a load beam in a dimension normal to the load beam plane. A load beam in a high shock suspension system comprises a planar body having transverse members extending between longitudinal rails. One embodiment comprises a lifter integral to the load beam, extending distally, and comprising a rib having a conic cross section and a lifting tab having upward curving edges. Another embodiment comprises rails having edges bending upward at 90 degrees, separated by a first width at a proximal end of the body, and tapering to a second width at a distal end of the body. A narrow lifter having upward curving edges is displaced between the rails, and extends distally from the body. Stiffeners extend from the rails and connect to an intermediate point on the lifter. Another embodiment comprises the body having a transition portion tapering in a distal direction to form a narrow lifter, and a 90-degree rail bordering the body, transition portion, and lifter. Other embodiments comprise: the body slanting upward at an slight angle and a lifter extending distally from the body; a lifter slanting upward then downward to a position parallel with a load beam plane; transverse members having curved edges; and protrusions located on a border between the body and an intermediate portion that tapers to a lifter.

摘要： A baseplate in a disk drive suspension system is configured with an integral anvil having a spring-forming edge that coincides with an optimal bend location on a linear flex spring. The spring attaches to upper surfaces of baseplate and load beam to allow for alignment of a rolling tool above the optimal bend location. During assembly, rolling tool pressure permanently bends the spring around the spring-forming edge to create a desired pre-load characteristic for the suspension system. The integral anvil may include a relief portion for reducing friction on the spring during the bending operation. A method for pre-loading a suspension assembly comprises forming an integral anvil on a baseplate, forming a spring-forming edge on the integral anvil, positioning an optimal bend location on the spring to coincide with the spring-forming edge, and forming a permanent bend in the spring by applying pressure on the spring around the spring-forming edge.
