摘要： A disc drive has a recording disc rotatable around an axis, a slider supporting a transducing head for transducing data with the disc, and a dual-stage actuation assembly supporting the slider to position the transducing head adjacent a selected radial track of the disc. The dual-stage actuation assembly includes a movable actuator arm, a suspension assembly supported by the actuator arm and including a flexure, a tongue supporting the slider, and a microactuator. The microactuator includes a rotor attached to the tongue and a stator attached to the flexure and operatively connected to the rotor to radially move the rotor with respect to the stator. At least one beam is attached between the slider bond pad and the stator.

摘要： A disc drive head suspension assembly includes a recording head, a load beam and a gimbal. The recording head includes a recording surface and a back surface. The load beam includes a front surface, a back surface, a distal end and a load protrusion. The load protrusion extends from the front surface of the load beam toward the back surface of the recording head. The gimbal is attached to the back surface of the load beam and includes a head mounting tab which is positioned beyond the distal end of the load beam. The recording head is attached to the head mounting tab. A first displacement limiter extends between the load beam and the gimbal, which limits vertical displacement of the gimbal in a direction toward the recording head relative to the load beam.

摘要： A disc drive suspension is provided, which includes a longitudinal axis, a rigid load beam section and a preload transfer section. The rigid load beam section extends along the longitudinal axis and has first and second opposing lateral side edges with respective first and second stiffening rails.

摘要： Non operational shock resistance is achieved by preventing separation of the read/write head from the disk. Embodiments include optimizing the normal stiction force of a lubricant topcoat by controlling the texture geometry of the landing zone and lubricant topcoat thickness, particularly the density of protrusions. Laser textured landing zones having a protrusion density above about 4,500 protrusions/mm.sup.2 can provide an optimal normal stiction force in excess of 25 gf per interface and a lateral stiction force below 10 gf per interface.

摘要： A suspension is provided, which has proximal and distal ends and a longitudinal axis extending from the proximal end toward the distal end. A rotating hinge rotates the distal end about the longitudinal axis in response to vertical motion of the distal end relative to the proximal end. In one example, the suspension includes a preformed twist deformation, which rotates the distal end about the longitudinal axis relative to the proximal end axis in a direction opposite to rotation by the rotating hinge, in response to the vertical motion.

摘要： A suspension is provided, which has a base, a load beam and a hinge structure. The hinge structure and at least one of the base and the load beam are formed of a single continuous piece of multiple layer laminate material, which includes first and second layers. The hinge structure includes a first beam formed by the first layer and a second beam formed by the second layer. The first layer is absent along the second beam and the second layer is absent along the first beam such that the first and second beams are vertically offset from one another. The first and second beams extend between the base and the load beam.

摘要： A dynamically symmetric actuator is disclosed for reducing off-track motion. The dynamically symmetric actuator of the present invention limits torsional or twisting motion of the actuator arm which reduces off-track motion. In one embodiment, the actuator arm includes a thickness step designed to balance stiffness of inner and outer portions of the actuator arm. The thickness step forms multi-thickness tiers, the dimensions of which can be modeled to optimize a first bending mode frequency of the actuator arm to further reduce off-track motion or errors.
