Abstract
A head suspension including a one-piece load beam and flexure structure wherein the flexure structure includes partially etched connecting bars. The load beam and flexure structure is fabricated from a single piece of spring steel, and the structure comprises a rigid region, a mounting region on a proximal end of the rigid region, and a flexure region. The flexure region has a planar support region and an integral flexure, and the integral flexure includes a slider-receiving region and connecting bars that connect the slider-receiving region to the support region of the integral flexure. A head slider is mounted to the slider-receiving region. The connecting bars of the integral flexure are thinned by partial etching in order to reduce the stiffness of the connecting bars, and thereby allow the head slider to gimbal in response to aerodynamic forces.
