Abstract
A disk drive head suspension having a leaf-type gram load spring. One embodiment of the suspension includes a base plate and a load beam. The load beam is formed from a single piece of stainless steel and includes a mounting region, a beam region, a spring region between the mounting region and beam region, and a leaf spring extending from the beam region. The mounting region of the load beam is attached to the base plate, with a proximal end portion of the leaf spring overlaying the base plate. The leaf spring can have a formed bend in the z-height direction and is forced into a loaded state before the proximal end is welded to the base plate.
