摘要： 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.

摘要： 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.

摘要： An integrated suspension for a hard disk drive is formed as a single-piece flat assembly. The design eliminates the need for mechanical reinforcement such as flange forming, and requires no additional weld processing to form the functional portion of the assembly. A partial etch process is used to reduce local thicknesses in the gimbal and hinge areas to reduce the overall stiffness of the suspension. The proximal end structure of the suspension is also built by partial etching to achieve higher natural frequencies. The suspension design also incorporates built-in load/unload features and two-sided, opposite-facing limiters to limit excessive slider displacement during the manufacturing process, loading/unloading, and non-operational shock environments.
