Abstract

A stepped suspension load beam is described, such as for a hard disk drive, in which the main body is composed of a proximal portion that lies in a first plane, an intermediate portion between the proximal portion and a distal portion and that lies in a second plane that angles upward from the proximal portion, and a distal portion that lies in a third plane that angles back down from the intermediate portion, thereby forming a load beam stepped in the longitudinal direction. Further, the proximal portion may be formed to taper in at a first angle, the intermediate portion formed to taper in at a second angle that is less than the first angle, and the distal portion formed to taper in at a third angle greater than the first and second angles, thereby forming a load beam stepped in the transverse direction.
