  • Patent number: 8559138
    Abstract: A dual stage actuator (DSA) suspension has a single microactuator such as a PZT element on one side of central longitudinal axis of the suspension, and a pseudo symmetry structure formed or affixed on the other side of the central longitudinal axis opposite the PZT. The pseudo symmetry structure has mass and stiffness that mirrors the PZT, thus keeping the suspension mechanically balanced and symmetric about the longitudinal axis for improved suspension performance especially in a shock environment.

  • Patent number: 8446695
    Abstract: For decreased pitch and roll stiffness, a ring gimbal suspension for a hard disk drive has torsion arms that extend toward the distal end of the suspension as they extend inward from the gimbal outer arms toward the slider bond pad. The torsion arms connect to the slider bond pad at a location that is distal of the dimple contact point. The electrical circuit traces are generally free of stainless steel except where the circuit traces cross the torsion arms, at which point they are affixed to the torsion arms. The electrical circuit traces can include an outward meander away from the slider bond pad as the traces pass over the torsion arms, for additional reduction in stiffness.

  • Patent number: 8441761
    Abstract: In a disk drive suspension circuit, in order to improve stability of the stable pitch static attitude (PSA) over changes in humidity, the suspended portion of the flexible circuit and/or the gimbal support arm are modified to change their response(s) to humidity. In one embodiment, hygroscopic material such as the material of the insulating layer are added to the stainless steel gimbal support arm, so that in response to humidity it bends in the opposite direction as the suspended portion of the circuit. In another embodiment, additional hygroscopic material is added to the circuit, and/or the polyimide insulating layer or the coverlayer are selectively removed, so that the net bend in the suspended portion of the circuit over humidity is reduced, ideally to a condition of zero or close to zero net bending.

  • Patent number: 8149545
    Abstract: A dual-stage actuator disk drive suspension load beam has a recessed cavity formed in it into which the microactuator motor is partially or completely placed. The cavity may be formed by partially etching the load beam during the same etching process that creates the load beam from a sheet of stainless steel material. The partially etched load beam having a cavity for the microactuator motor has the advantages of a lower profile, improved inertial balancing of the suspension, and increased sway resonant frequency.

  • Patent number: 7706106
    Abstract: Shock performance and stiffness of hard disk drive lifters are enhanced by extending one or more portions of a load beam in a dimension normal to the load beam plane. A load beam in a high shock suspension system comprises a planar body having transverse members extending between longitudinal rails. One embodiment comprises a lifter integral to the load beam, extending distally, and comprising a rib having a conic cross section and a lifting tab having upward curving edges. Another embodiment comprises rails having edges bending upward at 90 degrees, separated by a first width at a proximal end of the body, and tapering to a second width at a distal end of the body. A narrow lifter having upward curving edges is displaced between the rails, and extends distally from the body. Stiffeners extend from the rails and connect to an intermediate point on the lifter.
