Abstract: A slider suspension system for use in a magnetic recording disk file comprised of a laminated suspension positioned between an actuator arm and a read/write slider. The laminate is comprised of a copper alloy conductor layer, a polyimide dielectric layer and a stainless steel stiffener layer. A pattern of land areas are etched in the conductor layer and act as constraining areas for the viscoelastic dielectric layer. The constrained layer/constraining layer configuration damps vibrations existing in the suspension system.

Abstract: The improved disk drive system has an improved actuator arm assembly where the arms are independently and individually insertable and removable from the actuator member. Furthermore, each arm is individually self-locked into the actuator member without the need for external retaining means such as screws, springs, and rings. Since the arms are individually insertable/removable, the arms can be made very thin thereby allowing easy attachment of the head suspension assembly to the arm without the need for swaging, bonding, welding or screw-in. Since the arms can be made very thin, that provides substantial reduction in disk to disk spacing and therefore, substantial reduction in the overall height of a disk drive system.

Abstract: A suspension system for supporting a magnetic read/write slider comprises a load beam, a slider support member and a flexure comprised of a first flexure arm and a second flexure arm. The electrical conductors to the slider are positioned either along one or both flexure arms or adjacent to, but outside of, the second flexure arm, so as not to contribute to the stiffness of the second flexure arm. The electrical conductors are comprised of a laminated material which includes a conductor layer, such as a high strength copper alloy, a dielectric layer and a support layer. A first plurality of slots extend completely through the first flexible finger region, and a second plurality of slots extend completely through the second flexible finger region for providing regions into which the electrical conductors can move when the flexure undergoes deflections (see fig 12).
