Low mass sectioned load beam of head gimbal assembly having increased high first torsion frequency mode

摘要

A load beam of a head suspension assembly includes a base plate attachment segment, and an intermediate region that extends integrally from the base plate attachment segment. A bend region extends integrally from the intermediate region for providing the load beam with a predetermined preload spring force and for increasing the lateral stiffness of the load beam. A forward section extends from the bend region, so that the center of gravity of the bend region and forward section is shifted toward the base plate attachment in order to improve the shock performance of the load beam, and so that a moment arm of the bend region and the forward section is shortened. In a preferred embodiment the intermediate region is wider than the base plate attachment segment.
