• A 2-D dynamic model was proposed to describe the dynamic behavior of the ramp/lift-tab interface of a one-inch hard disk drive with consideration of the air bearing force and contact stages during the unloading process. The contribution of the geometric parameters of the ramp/lift-tab interface on the dynamic performance of the suspension lift-tab was studied through simulation. A modified Reynolds equation and an iterative formulation for numerical scheme were presented considering continuum Poiseuille flows. The dynamic model developed for the lift-tab motion was extended to simulate the contact and separation stages of head-disk interface subjected to external shocks.
