ABSTRACT:
The invention is several alternative means of differentiating head/gimbal assemblies that share a common arm. The alternative means are for at least one of the assemblies that shares a common arm (1) using a different design; (2) varying the length from the mounting section to the slider; (3) changing the shape of the spring section; (4) varying the use and shape of raised flanges; (5) varying the use and shape of stiffeners; (6) using different openings (i.e., cut away portions); (7) using different formed features; (8) using various mass appendages; and (9) using a varying pattern of adhesive or glue dots.
