Abstract:
A load beam of an HGA for use in a disc drive comprising:a mounting portion adapted to couple the load beam to a track accessing arm of the disc drive; a flexible beam portion attached to the mounting portion and adapted to supply a pre-load force; a flexure arm adapted to apply the pre-load force to a head; and a rigid beam section having a proximal end attached to the flexible beam portion, a distal end attached to the flexure arm, a longitudinal axis, a tooling hole located adjacent the distal end, and a high stress region having a plurality of apertures extending in rows from adjacent the tooling hole toward the distal and proximal ends, the rows being oriented at oblique angles relative to the longitudinal axis and defining high stress contours of the rigid beam section where plastic deformation is desired during roll static angle adjustment.
