Abstract
A head suspension assembly for a disk drive has elongated members, in the form of flat strips of stainless steel, which have distal ends welded to the mounting ends of stainless steel load beams with the load beam and the stainless steel strips in alignment. Magnetic heads are mounted in corresponding positions on the distal ends of the load beams. The stainless steel strips are welded together at their distal ends with the load beams aligned with one another and the magnetic heads on the distal ends of the load beams facing in opposite directions. The stainless steel strips are of the same thickness as the reinforcing plates or swage plates which they replace. The load beams are spaced apart by the combined thickness of the stainless steel strips. An arm of an actuator is positioned between and secured to the mounting ends of the stainless steel strips, providing an A-frame type of structure which is light in weight, dimensionally stable and rigid. The A-frame structure is of reduced thickness with respect to conventional head suspensions, permitting closer disk spacing and replaces a corresponding length of heavier conventional arm structure to thereby reduce head suspension iner…
