US 9,870,792 B2 · Disk drive suspension assembly having a partially flangeless load point dimple

Abstract

Various embodiments concern a suspension assembly of a disk drive. The suspension assembly includes a load beam comprising a major planar area formed from a substrate. The load beam further comprises a window in the substrate, a dimple formed from the substrate, and a flange. The flange is a region of the major planar area that extends partially around the dimple but does not extend along an edge of the dimple. The edge of the dimple is adjacent to the window. The dimple is in contact with the flexure. A HAMR block or other element can extend through the window. The lack of a full flange can minimize the necessary clearance between the dimple and the HAMR block or other element and thereby allow the window to be enlarged to accommodate the HAMR block or other element.
