    摘要： A head-gimbal assembly for suspending a magnetic head over a spinning disk in a magnetic disk drive having head suspension positioning apparatus includes a base plate fastenable to the positioning apparatus in the magnetic disk drive, a load beam coupled at one end thereof to the base plate and a first dimple in the load beam at another end thereof, a flexible gimbal coupled to the load beam near the other end thereof and a second dimple in the gimbal having a concave surface facing a convex surface of the first dimple and a convex surface to which the magnetic head is attachable. Preferably, the convex surface of the first dimple has a radius smaller than a radius of the concave surface of the second dimple. The head is attached to the gimbal by an adhesive material attached to the convex surface of the second dimple and a top surface of the magnetic head. The adhesive material is hardened while a bottom surface of the head and the base plate are held in a predetermined attitude relative to one another (e.g., parallel to one another). Preferably, a predetermined force is applied to the head-gimbal interface while the adhesive material hardens corresponding to (e.g., equal to) an operational force exerted on the head-gimbal interface during operation of the magnetic disk drive.

    摘要： A gimbal embodying the present invention couples the magnetic head to the load beam through torsion fingers which twist to permit rotational motion of the head in one degree of freedom (e.g., pitch or roll) and bending arms which bend to permit rotational motion of the head in the other degree of freedom. Lateral separation of localized bending regions of the arms, and a dimple, serve to prevent motion of the head in other rotational and translational degrees of freedom.

    摘要： A tolerance ring configured to reduce torque ripple for a pivot bearing in an actuator arm assembly. The tolerance ring comprises a cylinder having a predetermined length, and a first and a second row of contacting portions arranged around the surface of the cylinder, the contacting portions of the second row are circumferentially displaced with respect to the first row by a distance greater than zero but less than the distance of the contacting portion and the spacing between adjacent contacting portions in the first row.

    摘要： A method for reducing surface particle shedding of a material, specifically a suspension mounting arm for a hard disk drive, made of an alloy such as 300 Series stainless steel, by thermally conditioning the mounting arm for a desirable time period sufficient to reduce residual stress in the mounting arm while substantially maintaining its original yield strength characteristics. To ensure fabrication free from oxidation and contamination, the contained heat source can be oxygen depleted by evacuating the interior of the container to a sub-atmospheric pressure or by filling the interior of with an inert gas such as argon or a reducing gas, such as hydrogen. After thermal exposure, the material is cooled to an ambient temperature. The resulting material exhibits adequate stiffness and yield strength for assembly and operation in a hard disk drive.

    摘要： A tolerance ring for applications requiring high axial static friction has contacting portions having a novel profile. The use of multiple contacting portions having a smaller size that are wedge-shaped increases rigidity and provides a directional grip that increases axial static function. Using multiple wedge-shaped contacting portions with appropriate opposite slants provides a balanced and symmetrical grip. Using inter-level wedge-shaped contacting portions with opposite slants provides a more aggressive grip while providing a tolerance ring that is more dynamically stable and has a high resonant frequency.

    摘要： A tolerance ring for coupling an actuator arm to a pivot bearing while maintaining mass eccentricity of the actuator arm. The tolerance ring having a substantially cylindrical base portion with a first radius about a central axis and extending a length parallel to the central axis, the cylindrical base portion has a first tab and a second tab extending along the length of the cylindrical base portion, the first tab being positioned proximate to the second tab. The tolerance ring improves mass eccentricity by radially displacing the first tab at a second radius about the axis such that a radial gap is formed between the first tab and second tab.
