Abstract:
A disc travel limiter for preventing contact between a disc and a pair of actuator head mounting arms disposed adjacent opposing surfaces of the disc in a disc drive comprising:a backing member disposed beyond an outermost diameter of the disc; and a pair of limiter arms extending from the backing member, each limiter arm adjacent a respective surface of the disc and comprising: a first cantilevered member extending at a first distance from the respective surface and having a proximal end affixed to the backing member; and a second cantilevered member extending substantially parallel to the first cantilevered member at a second distance from the respective surface greater than the first distance so that a gap is formed between the first and second cantilevered members, wherein the first cantilevered member is operationally configured to deflect when the disc contacts the limiter arm and wherein the second cantilevered member is operationally configured to limit the deflection of the first cantilevered member when the first cantilevered member contacts the second cantilevered member.
