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 suspension load beam for carrying a slider and read/write head elements in a magnetic data storage device is formed from a composite laminate material sheet that includes first and second primary layers respectively comprising first and second structural load bearing material sheets sandwiching an intermediate secondary layer comprising a third structural load bearing material sheet. The secondary layer is made of a different material than either of the first and second primary layers. One or more areas of reduced thickness are etched into one or both of the primary layers down to the secondary layer at one or more locations on the laminate material sheet.
