Abstract

This study investigated the effect of design parameters of a 2.5 inch HDD on the operational shock (op-shock) performance, including the base, cover, ramp stiffness, and the e-block, disk thickness. First, transient shock simulation model was constructed with a nonlinear contact model. From this shock model, the relative displacement between slider and disk is extracted and the vertical force and moment between the slider and disk are calculated. Then, the slider dynamics were analyzed to investigate the characteristics of the head disk interface (HDI) in response to input shock. The input shock is the pulse that is extracted from the transient shock simulation. Finally, the effects of the design parameters on operational shock performance were investigated.
