摘要： Embodiments of disk drive head suspensions are described that include a spring metal layer. The spring metal layer includes a base region, support arms extending from the base region, and a slider mounting region. The slider mounting region includes a proximal portion, a distal portion, and a pair of motor openings. The motor openings are configured to receive motors such that the longitudinal axes of the motors are non-parallel with the longitudinal axis of the slider mounting region. The suspensions include traces that include a base portion on the base region of the spring metal layer, a spring metal-unsupported portion extending from the base region to the slider mounting region, and a slider mounting portion extending from the spring metal-unsupported portion onto the slider mounting region. And, the suspensions include an insulating layer between portions of the spring metal layer and the conductor layer.

摘要： Various embodiments concern a gimbaled flexure having a dual stage actuation structure. The flexure comprises a gimbal on which a motor is mounted. The motor comprises a first and second terminals and a plurality of actuator layers formed from a piezoelectric material. The plurality of actuator layers comprise serially stacked first, second, and third actuator layers. The plurality of actuator layers are respectively poled and connected to the first and second terminals such that both of the first and second actuator layers expand while the third actuator layer contracts in response to application of a signal across the first and second terminals. The differential motion of the plurality of layers in the motor cause the motor to curl about the contracting third actuator layer. The curling motion causes a portion of the flexure to preferentially curl.

摘要： Various embodiments concern a dual stage actuation flexure having a motor contact paddle for connecting to a terminal of a piezoelectric motor. The flexure comprises a paddle having a top side and a bottom side, the paddle comprising at least one void, each void extending through the paddle from the bottom side to the top side. The paddle further comprises a stainless steel base, a conductor comprising a layer of metal, and a dielectric layer having a first section and a second section, the first section positioned between the conductor and the stainless steel base to overlap the stainless steel base and the second section extending beyond the stainless steel base to not overlap the stainless steel base. The bottom side of the paddle is configured to connect to the terminal with electrically conductive adhesive.
