摘要： A head suspension assembly for a rigid disk drive. The load beam has a mounting region at a proximal end, a rigid region at a distal end and a spring region connecting the mounting region and the rigid region. A pair of rails extend along a portion of the rigid region. The rigid region has a railed region and a non-railed region adjacent to the spring region. A stiffener is attached to the load beam in a multi-layered structure. The stiffener has a proximal portion extending along at least a portion of the non-railed region without extending into the spring region, and a distal portion extending along 50% or less of a length of the railed region closest to the spring region.

摘要： A method for manufacturing a disk drive head suspension including a load beam, a flexure and a limiter for restricting the range of motion of the flexure with respect to the load beam. The load beam includes an aperture and an engaged portion adjacent to the aperture. The flexure, in an unformed state, includes a slider mounting region and a generally planar engagement structure extending from the slider mounting region. The engagement structure includes a tab portion extending from the slider mounting region and a hook portion extending from the tab portion. During a first forming operation the hook portion is bent around a tooling die to a ninety degree angle with respect to the tab portion. The flexure is then welded to the load beam with the hook portion extending into the aperture. During a second forming operation the tab portion is bent around a tooling die to a ninety degree angle with respect to the slider mounting region. The second forming operation causes the hook to extend over the engaged portion of the load beam. The first and second forming operations can be performed with tooling moving only in a z-direction.

摘要： A head suspension for supporting a head slider relative to a rotating disk in a rigid disk drive, formed from a flexure and a load beam that has a mounting region, a rigid region and a spring region located between the mounting and rigid regions. The load beam including a shock limiter integrally formed within the spring region as a cantilevered portion surrounded by a spring aperture used for adjusting the spring stiffness of the spring region. The head suspension typically configured to include a bend or radius in the spring region to bias the head suspension toward the disk surface. The cantilevered portion of the shock limiter formed with a pre-determined gap between the shock limiter and the head suspension when the head suspension is in an operating position. The cantilevered portion configured to overlap a portion of the head suspension, such that movement of the head suspension toward the shock limiter due to impact or shock loading results in contact between the shock limiter and the overlapped portion, thereby arresting the movement of the head suspension.
