Abstract
An improved crash stop apparatus having an inner crash stop that pressingly engages the actuator assembly of a disc drive when the read/write heads of the actuator assembly approach a desired inner extent of radial travel to prevent further movement of the read/write head beyond the inner extent of travel and furthermore having an outer crash stop that pressingly engages the actuator assembly when the read/write heads approach a desired outer extent of radial travel. The crash stops each have a pin rigidly mounted at a proximal end and having a cantilevered distal portion which is disposed in the path of travel of the actuator. An elastomeric member is disposed between the impacting actuator and the pin. The elastomeric member and cantilevered pin provide a two-stage braking impulse to decelerate the actuator, wherein the first stage compresses the elastomeric member and wherein the second stage deflects the cantilevered pin.
