Abstract
An actuator for a disk drive is disclosed. The actuator includes a plurality of arms including an upper outer arm, a lower outer arm, and at least one inner arm. The outer arms each include a region of reduced width and also include a region of increased thickness, both such regions being located closer to a proximal supported end of the outer arm than to its distal end. Each region of increased thickness has a minimum thickness that is more than the thickness of the inner arm at an equal distance from the axis. Each region of reduced width has a minimum width that is less than the minimum width of the inner arm at an equal distance from the axis.
