Abstract: A tolerance ring configured to improve mass eccentricity of an actuator arm assembly. The tolerance ring has a cylinder with a predetermined length between two ends, with a gap along the predetermined length of the cylinder, the gap having a first and a second edge, the cylinder having an aperture in the surface of the cylinder at the second edge.

Abstract: A damper for a data storage device having a viscoelastic material and a constraint material disposed on the viscoelastic material, the constraint material covers the sides of the viscoelastic material to reduce exposure of the viscoelastic material from debris in the surrounding environment.

Abstract: A tolerance ring configured to prevent interlocking during shipping and handling. The tolerance ring has a cylinder with a first radius about an axis of rotation and a gap in the cylinder surface having a first edge and second edge extending along the axis. The gap in the cylindrical base has a first tab on the first edge and a second tab on the second edge. The first tab is adapted for coupling to the second tab and thereby prevents the interlocking of one tolerance ring with another. The gap can be configured to be non-linear.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A swage mount for a recording head suspension comprising a flange, and a hub made of a base metal extending from the flange, and at least an outer surface of the hub is plated with one or more layers of metal which provides increased retention torque, and/or increased cleanliness, and/or increased corrosion resistance. This invention may be used in conjunction with swage mounts that contain surface protrusions that are intentionally created (such as chromium nitride or chromium carbide protrusions) or not intentionally created (such as material inclusions or embedded media particles). In this case the metal plating helps prevent separation of the protrusions from the swage mount, thereby helping to prevent contamination.

Abstract: A disk drive has a head stack assembly with head arms which extend between adjacent magnetic disks. Each head arm includes head gimbal assemblies. The head arm is capable of pivoting about a first axis of rotation for providing the head gimbal assembly with a macro-actuation movement relative to a selected track on a disk, and for positioning the head gimbal assembly in an initial position relative to the selected track. A micro-actuator is connected to the head gimbal assembly so that the head gimbal assembly is pivotally secured to the head arm about a second axis independently of the pivotal movement of the head arm. This provides the head gimbal assembly with a micro-actuation movement relative to the selected track, such that if there is skew between the head gimbal assembly and the track, a micro-actuator provides correction to minimize the skew angle. Also the micro-actuator provides cancellation of transient and harmonic vibrations.

Abstract: 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.
