Abstract: An integrated gimbal suspension includes a flexure with an integrated, built-in gimbal, and includes a limiter structure that constrains motions of the gimbal in multi-degrees of freedom. The limiter structure includes one or more tab-shaped limiters and corresponding stops integrally formed into the gimbal assembly at strategic locations, which interact to provide the desired constraints to the motions of the flexure gimbal to prevent permanent damage from over-straining the gimbal or flexure beyond its designed range. The limiters may be pre-formed tab-shaped structures that are bent from the plane of the flexure. As the gimbal moves from its nominal position, one or more limiters engage the stops before such motion reaches the limit of the designed range of motion of the gimbal.

Abstract: A transducer suspension system is comprised of a load beam and a flexure. The flexure has a platform for receiving a transducer head. The platform has a forward portion which has a forward facing tab which engages an aperture in the load beam above. The rear portion of the platform has a pair of forward facing rear tabs which engage an aperture in the load beam above. The tabs limit the motion of the flexure during violent shocks, thereby preventing damage to the flexure.

Abstract: A hard disk drive has actuator arms with a load beam or suspension extending from one end. Each suspension carries an integrated lead layer with electrical traces which are connected to a magnetic read/write heads for interacting with magnetic disks in the disk drive. Each suspension also has a pair of polymer pads on each side of the traces. Each pad has a series of bumps which give the pads a greater thickness than the lead layer for preventing contact between the traces, suspensions and magnetic disks during shock vibration. The pads also prevent contact between the trace conductors and the head separator during the separation process.

Abstract: Disclosed is an integrated lead suspension flexure attachment structure for a micro-actuator with a slider/transducer assembly attached thereto, having a plurality of electrical terminals for both the micro-actuator and the transducer. The suspension provides low gimbal stiffness and allows the slider to have correct pitch and roll static attitudes. An attachment platform is provided for mechanically attaching the micro-actuator. Two elongate cantilever compliance members extend from the transducer edge and the opposite edge of the attachment platform. Two lead termination platforms are provided, each at the distal end of one of the compliance members. The lead termination platforms extend laterally to either side of the compliance members. Electrical leads are positioned laterally of each of the lead termination platforms on either side, and loop towards the compliance member to the lead termination platform to reduce stiffness of the leads. The two lead termination platforms each supports the electrical leads at either side of the compliance member and the compliance members allow flex between the attachment platform and the lead terminations for connecting the leads to the micro-actuator.

Abstract: A disk drive includes a suspension assembly that includes a load beam and a laminated flexure. The laminated flexure includes a structural layer, a dielectric layer, and an electrically conductive layer. The electrically conductive layer includes a plurality of flexure bond pads. The structural layer includes a tongue and a flexure bond pad shelf. The flexure bond pad shelf underlies each of the plurality of flexure bond pads. The flexure bond pad shelf is separate from the tongue in the structural layer so that the structural layer nowhere connects the flexure bond pad shelf to the tongue. A fine actuator may be disposed on and bonded to the tongue to produce relative motion between the head and the tongue. With the flexure bond pads bonded to the plurality of head bond pads, the fine actuator may also produce relative motion between the flexure bond pad shelf and the tongue.
