摘要： A disk drive suspension has laterally separated mount plate cooperating structure of a pair of spaced, left and right hand continued extents defining engagement structures extending into the vertical plane of the suspension hinge portion, and laterally separated beam portion cooperating structure of left and right hand continuations defining cooperating engagement structures also extending into the vertical plane of the hinge portion and overlapping the mount plate extents to block their relative vertical movement in one direction but not the other so that rotation of the beam portion relative to the mount plate is limited by this selective engagement of the cooperating structures, while the hinge portion is untrammeled by the cooperating structures and the suspension has increased torsional stiffness without an increase in suspension vertical stiffness or has a decrease in suspension vertical stiffness without a decrease in torsional stiffness.

摘要： A suspension assembly for a hard disk drive includes at least two spring extensions that couple to a proximal portion of a load beam. These spring extensions are disposed by a vertical offset and couple to the load beam on opposite sides of a longitudinal axis of the load beam. The method for operating a disk drive apparatus includes following by a suspension assembly from a reference position to a second position a vertical movement of a rotating disk. The suspension assembly is predisposed to move from the reference position to the second position by the vertical offset. A read/write head coupled to the suspension assembly is in closer alignment to a selected track during the vertical movement in the second position than if the first and second spring extensions were disposed to be co-planar.

摘要： A support arm for use in a disc drive suspension includes an asymmetry that creates a vertical coupling in the support arm, i.e., a slight lateral movement of the support arm distal end to which a load beam is mounted in response to vibration-induced bending of the support arm. The vertical coupling in the support arm at least partially cancels out during arm bending any vertical coupling which has been designed into the coupling between the load beam and the support arm to reduce track misregistration during flow-induced vibrations of the disc surface. In this way, track misregistration during both flow-induced vibrations and during arm bending is reduced. In a preferred embodiment the asymmetry is created by at least one of a first notch along an inside top edge of the arm, and a second notch along a bottom outside edge of the arm.

摘要： Structures and methods for creating a vertical offset between suspension springs or fingers within a suspension head assembly for use in a disk drive are disclosed, the vertical offset helping to reduce track mis-registration errors. The base plate and load beam may be made from three-layer composite materials that have been etched to create either recesses therein into which the suspension springs ends are placed and then welded, or the base plate and load beam may be etched to create mesas on which the ends of one of the suspension springs are welded. The three layers may comprise stainless steel, polyimide, and stainless steel. In another embodiment, one of the suspension springs is a three-layer material that has been etched to create a raised central portion that is vertically offset from the other suspension spring. In another embodiment, spacers are employed as shims underneath one of the suspension springs. Generally, at least one of a spring extension, the load beam and the mount beam comprise a laminate material.

摘要： A structure for a load beam used in hard disk drive devices includes an asymmetric structure. The load beam exhibits longitudinal asymmetry (i.e., is asymmetric along its long axis) in regard to the weight distribution, but has a center of mass that lies along its longitudinal axis due to the provisioning of counterbalancing features, such as the addition of material, the removal of material, or a combination of adding material and removing material, or the use of an asymmetrical damping layer.

摘要： Techniques for preventing electrostatic discharge (ESD) and circuit noise are provided. More particularly, the present invention provides a method to prevent ESD damage during the assembly of computer disk commonly called a hard disk for memory applications. The coating mainly involves a ion-deposition process. Merely by way of example, the present invention is implemented by using filtered cathodic vacuum arc (FCVA) with a dissipative crystalline and/or amorphous carbon base thin film coating on a flexible circuit to drain the potential electrostatic charges during circuit assembly and interconnect processes, yet it would be recognized that the invention has a much broader range of applicability on any electronic apparatus that is susceptible to electrostatic damage and static noise.

摘要： A disk drive suspension has a load beam having a base, a flexure for carrying a slider, and a mount plate. The suspension mount plate has a first portion attachable to an actuator and movable by the actuator as the primary shifting force on the load beam, suitable for larger positioning movements. A second portion of the mount plate is attached to the load beam base and is movable relative to the mount plate first portion. A microactuator moves the second mount plate portion relative to the first mount plate portion as a secondary shifting force on the load beam, suitable for very small positioning movements.
