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; anda pair of limiter arms extending from the backing member, each limiter arm adjacent a respective surface of the disc and comprising:a cantilevered member which extends at a first distance from the respective surface and comprises a proximal end affixed to the backing member; anda radiused contact surface which projects from a distal end of the cantilevered member and tapers toward the respective surface to a second distance from said surface less than said first distance so that the disc contacts a portion of the radiused contact surface when the disc is deflected in response to application of a mechanical shock to the disc drive.
