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.

摘要： One embodiment of the present invention provides a unified suspension that includes an integral, continuous laminate, which has a thick actuator arm portion, a thin pre-load portion, and a beam portion, all formed of the same single laminate. The pre-load portion is integrally connected to the actuator arm portion, is thinner than the actuator arm portion, and is configured to apply a pre-load force. The beam portion is integrally connected to the pre-load portion, and is configured for attaching a gimbal to it. This integral, continuous laminate substantially lowers the mass of the suspension, provides excellent shock, resonance and lift tab performance, lowers power consumption requirements, and simplifies the complexity and cost of manufacturing components for a suspension and for assembling the components of the suspension together and into a larger system of which the suspension is a part.

摘要： A suspension for a storage device includes a metal layer and one or more composite stiffeners bonded to the metal layer to stiffen part but not all of the suspension. The composite stiffeners are made of a composite material and are bonded to the metal layer by an adhesive. Under most embodiments, the composite material has a higher stiffness to weight ratio than a metal.

摘要： The present invention provides a system, method and apparatus for controlling the coverage of an adhesive bond area between a suspension and a flex circuit interconnect by etching an area of the suspension to create a bonding area. The etching process prevents bonding of the flex circuit interconnect to the suspension in a tail and a side region allowing movement between the flex circuit and suspension, wherein the movement dampens a first torsion resonance mode. Better control of the bonding area between the interconnect and the suspension using the “adhesive down” helps reduce the variation in the roll stiffness of the suspension thereby reducing the fly height variation.
