Abstract: The pitch static attitude of a slider in an integrated lead suspension head gimbal assembly of a disk drive is controlled at the manufacturing stage. The integrated lead suspension includes a load beam, a mount plate, a hinge and a flexure made out of a multi-layer material. The flexure legs and the outrigger leads are simultaneously plastically deformed to define the pitch static attitude. The flexure legs and the outrigger leads are deformed at approximately the same longitudinal location.

Abstract: A method is provided for controlling the pitch static attitude of a slider in an integrated lead suspension head gimbal assembly. The integrated lead suspension includes a load beam, a mount plate, a hinge and a flexure made out of a multi-layer material. Localized heating is applied to the outrigger leads during the process of forming flexure legs to set a stable pitch static attitude, which does not change, by subsequent thermal exposures.

Abstract: A rotary microactuator includes a stationary structure formed on a substrate, a movable structure, and at least a pair of wires connected to the movable structure that conduct a signal associated with the movable structure. Each wire of the pair of wires has a first end that is connected in a cantilever manner to the substrate and a second end that is connected to the movable structure. The wires each have a serpentine shape between the first end and the second end, a predetermined spring stiffness, and a predetermined electrical characteristic. The microactuator also includes a magnetic head slider that is attached to the movable structure, and at least another pair of wires conducting a signal associated with a magnetic head of the slider. Each of the another pair of wires has a first end that is connected in a cantilever manner to the substrate and a second end that is connected to the movable structure. Like the first pair of wires, each of the another pair of wires has a serpentine shape between the first end and the second end of the wire. Electronic circuitry for conditioning the electrical signals associated with the magnetic head can be fabricated as part of the substrate and be connected to one of the pair of wires. The electronic circuitry can, for example, amplify electrical drive signals associated with the magnetic head, be a recording sensor preamplifier, and/or provide ESD protection for the electrical signals associated with the magnetic head.

Abstract: A transducer suspension system has a transducer head, laminated member, and a load beam. The laminated member is comprised of a support layer, an electrically insulating layer, and an electrically conducting layer. The electrical lines are formed directly into the laminated member. A first end of the support layer has an aperture into which a tongue section protrudes. The transducer head is attached to the tongue section. A platform section is formed between the aperture and the end of the support layer. The electrical lines run to the transducer head along the platform section. The load beam is attached to the laminated member and provides rigid support. The load beam has an aperture located directly above the platform section and provides access to allow clamping of the electrical lines and the platform section during electrical attachment of the lines to the transducer head. Precise electrical attachment is achieved without unwanted bending of the delicate flexure section of the suspension.

Abstract: Disclosed is a flying head slider and suspension assembly with a stress relief for minimizing the stress between a slider having a first linear coefficient of thermal expansion, and a suspension having a surface for adhering the head slider, the suspension having a second linear coefficient of thermal expansion greater than the first linear coefficient of thermal expansion. The flying head slider may be employed for recording and reproducing data on a magnetic disk of a magnetic disk file. One embodiment of the stress relief comprises an opening in the suspension separating the adherence surface into separate portions, each portion for adhering a portion of the head slider, and connected by formed legs on either side of the opening. Another embodiment comprises at least one shaped bumper between the surface and the head slider to provide a uniform thickness of adhesive for adhering the head slider. A further embodiment comprises a reduced thickness portion of the suspension at the surface which is less than the total area of the adherence surface. If the suspension is an integrated lead suspension having several layers which are selectively etched, the same processes and the same layers may be used for producing the stress relief.
