Abstract:
An actuator assembly for suspending and positioning a read/write head over a substantially flat surface of magnetic media, the actuator assembly comprising:an actuator arm having a distal end mating surface that includes asperities intentionally formed on the mating surface;a head suspension assembly (HSA) having a distal end for supporting the read/write head and a proximal end mating surface that includes asperities intentionally formed on the mating surface; andmeans for assembling the HSA to the actuator arm so that the asperities on the proximal end mating surface of the HSA engage the asperities on the distal end mating surface of the actuator arm to increase frictional coupling between the mating surfaces and reduce relative motion of the two mating surfaces when the actuator assembly is subjected to a mechanical shock.
