Abstract
A suspension assembly for a magnetic storage device. The suspension assembly includes a base plate, a load beam, and a flexure. A hinge of the load beam is configured to flex so that a distal end portion of the load beam moves relative to the base plate. The flexure includes a hinge portion and fixed portions adjacent the hinge portion. Each one of the fixed portions of the flexure includes a first layer and a second layer. The first layer is interposed between the second layer and the load beam. The hinge portion of the flexure includes the second layer but does not include the first layer. A thickness of the second layer of the hinge portion of the flexure is less than a thickness of the second layers of the fixed portions of the flexure.
