Abstract

The dynamics of the head/disk interface and the lift-tab ramp interface of hard disk drive subject to an external shock during load/unload process were modeled and simulated. The effects of the shock duration and amplitude of shock impulse on the dynamic and contact characteristics of related interfaces were analyzed. The results show that the effects of the shock on contact force and displacement response of dual sliders are different. The influence of the impact on the upper slider is greater than the lower one. These results are beneficial to the improvement of the head/disk interface and further application of the load/unload technology.
