摘要： A data storage device includes at least one head supported by an actuator arm. The at least one head interacts with the at least one data storage disc when positioned over the at least one data storage disc. The data storage device further includes a split ramp for supporting the at least one head when the at least one head is moved away from the at least one data storage disc. The split ramp has a first ramp portion adjacent to a first outer diameter (OD) of the at least one data storage disc and a second ramp portion adjacent to the first ramp portion, such that the first ramp portion is between the second ramp portion and the first OD. At least one of the first ramp portion or the second ramp portion is independently moveable.

摘要： Various embodiments concern a suspension having a DSA structure on a gimbaled flexure. The suspension comprises a loadbeam and flexure attached thereto. The flexure comprises a pair of spring arms, a tongue located between the spring arms and structurally supported by the pair of spring arms, and a pair of struts. The struts are positioned respectively between the pair of spring arms and the tongue. The longitudinal axes of the struts are offset with respect to each other. The suspension further comprises a slider and a motor mounted on the flexure. The motor has a longitudinal axis that is parallel with the axes of the struts and perpendicular to a longitudinal axis of the loadbeam. Electrical activation of the motor bends the pair of struts to move the slider.

摘要： An electrical interconnect from a suspension electrical circuit to a PZT microactuator motor includes copper plated onto a first side of a stainless steel support layer and gold plated onto a second and opposite side of the stainless steel support layer, with the gold plated stainless steel surface bonded to the PZT motor surface by conductive epoxy. The stainless steel may have a via etched into it to the copper surface before the gold plating step which then plates both the stainless steel and the copper with gold, so that the conductive epoxy is in physical and electrical contact with both the gold plated stainless steel and thus in electrical contact with the copper, and also in direct physical and electrical contact with the gold plated copper.
