Abstract :
Dynamic absorber is introduced to assist in controlling the amplitude and acceleration of the actuator arm in disk drive so that it can improve the shock handling capability in both operation and non-operating condition. The effect of the dynamic absorber on shock performance is examined through numerical simulation and experimental test.
