A disk drive head suspension headlift formed from a single piece of stainless steel includes a beam region, lift tab and offset region between the beam region and lift tab. The beam region has a major surface and formed side rails. The lift tab is a coined, trough-shaped member at a z-height spaced from the major surface of the beam region. The offset region has a major surface and side rails that transition in height between the side rails of the beam region and the lift tab.

Coined headlift with formed rail offset for a disk drive head suspension component

A disk drive head suspension, including a load beam formed from one or more layers of material, and a flexure mounted to the load beam. The load beam has an offset aperture and stiffening rails, and is characterized by a Z-height dimension between the one or more layers of material and the free end edges of the stiffening rails. The flexure has a slider-receiving region extending at least partially through the offset aperture and located within the Z-height dimension of the load beam. A load point structure is provided on the load beam and/or the flexure for restraining movement of the slider receiving region and for permitting slider-receiving region to pivot in under aerodynamic forces.
