Abstract
A gimbal design for a hard disk drive are disclosed. In one embodiment, a gimbal tongue is supported by a gimbal cross bar coupled to a suspension body by a pair of gimbal struts. A pair of grounding pads are mounted on either side of the leading edge of the gimbal tongue. A first limiter tab is coupled to the leading edge of the gimbal tongue and a second limiter tab is coupled to the trailing edge of the gimbal tongue. Notches on either side of the trailing edge limiter tab increase the strength of the tab. One or more cutouts allow the slider to be electrically coupled to bonding pads on the opposite side of the gimbal tongue. Angled slots at the juncture of the gimbal cross bar and the gimbal tongue relieve stress on the gimbal.
