A flexure for mounting a head in a hard disc drive. The gimbal of the flexure includes a load point tab which retains the full thickness of the original flexure material for most of its area and further includes a thinned area local to and surrounding a desired location for a load point button. The thinned area is formed out-of-plane from the remainder of the flexure by approximately one-half the material thickness. The size of the thinned area is selected to be such that the thinned area is substantially non-compliant under intended load forces.

An elongated disc drive magnetic head mounting flexure with integral gimbal, the flexure formed from a single piece of planar material having a first material thickness and comprising: a load beam; a first tab of the integral gimbal extending from and substantially coplanar with said load beam, said first tab having a first portion and a second portion, said first tab retaining the first material thickness except in a thinned area of the first portion local to and surrounding a selected location of a load point button defined in the first portion, the load point button also retaining the first material thickness and the thinned area having a second material thickness less than said first material thickness, the load point button being positioned out-of-plane from said second portion of said first tab by an amount equal to substantially one-half of the first material thickness; a second tab of the integral gimbal, also integral with said load beam, longitudinally spaced from said first tab, the second tab providing a head mounting surface; and a pair of laterally disposed partially etched longitudinal beams of the integral gimbal connecting said first and second tabs.
