ABSTRACT:
A head suspension includes a two piece construction including a load beam and a separately formed flexure wherein the assembly and construction facilitates the need for less space between disks within a disk drive. More specifically, the thickness of the flexure member need not be factored into the height of the load point dimple. The load point dimple height need only facilitate pitch and roll slider movements; thus, reducing the side profile of the head suspension. Moreover, the present invention allows for the use of load point dimples which are formed within the thickness of the load beam material, which can further reduce the side profile. In one aspect, a mounting surface of the mounting portion is provided on an opposite side of the load beam than the side of the load beam from which the load point dimple extend. The load portion can be also provided with a reduced thickness area with the load point dimple within the reduced thickness area. Alternatively, with the provision of a reduced thickness area the mounting surface of the mounting portion can be provided on the dimple side of the load beam with each of its spring arms including an offset bend for providing a first surface portion of each spring arm that is spaced closer to a level of a surface of the reduced thickness area.
