摘要： A head suspension assembly for a rigid disk drive. The load beam has a mounting region at a proximal end, a rigid region at a distal end and a spring region connecting the mounting region and the rigid region. A pair of rails extend along a portion of the rigid region. The rigid region has a railed region and a non-railed region adjacent to the spring region. A stiffener is attached to the load beam in a multi-layered structure. The stiffener has a proximal portion extending along at least a portion of the non-railed region without extending into the spring region, and a distal portion extending along 50% or less of a length of the railed region closest to the spring region.

摘要： A headlift on a distal end of a load beam of the type for use in a disk drive suspension, including two distally extending rails transversely spaced from each other, a cross member extending between the first and second rails, and a tab extending from the cross member. The headlift may include arms extending transversely from each rail that engage with each other and with an offset formed in the load beam. In one embodiment, the headlift is integrally formed from the same piece of material as the headlift. In a second embodiment, the headlift is formed from a polymer and attached to the load beam. The method of manufacture, in one embodiment, includes providing a unitary flat load beam member and folding the load beam member and attaching portions of the headlift to the load beam to form the headlift. Alternatively, the load beam may be formed with a structural surface that interfaces with a mounting portion of the headlift.

摘要： A method for manufacturing a disk drive head suspension including a load beam, a flexure and a limiter for restricting the range of motion of the flexure with respect to the load beam. The load beam includes an aperture and an engaged portion adjacent to the aperture. The flexure, in an unformed state, includes a slider mounting region and a generally planar engagement structure extending from the slider mounting region. The engagement structure includes a tab portion extending from the slider mounting region and a hook portion extending from the tab portion. During a first forming operation the hook portion is bent around a tooling die to a ninety degree angle with respect to the tab portion. The flexure is then welded to the load beam with the hook portion extending into the aperture. During a second forming operation the tab portion is bent around a tooling die to a ninety degree angle with respect to the slider mounting region. The second forming operation causes the hook to extend over the engaged portion of the load beam. The first and second forming operations can be performed with tooling moving only in a z-direction.

摘要： An improved dual stage actuated disk drive head suspension in accordance with one embodiment of the invention includes a mounting/base plate having first and second portions connected by a linkage, one or more PZT motors and a flexure having one or more pairs of differential drive signal traces. Each PZT motor has a pair of electrodes. Non-conductive adhesive secures each PZT motor to the first and second portions of the mounting/base plate with the electrodes of each motor being electrically isolated from the mounting/base plate. Each pair of drive signal traces is electrically connected to one of the pair of PZT motor electrodes to couple differential electrical drive signals to the PZT motor. Each PZT motor drives the first and second portions of the mounting/base plate with respect to one another in response to the drive signals.
