Abstract

This research proposes an operational shock analysis method that considers contact between a disk and the parking ramp for 2.5 inch stamped base HDD. The 2.5 inch stamped base HDD is susceptible to the external shock. The external shock increased the possibility of contact between disk and ramp. The contact between disk and ramp affect to the dynamic behavior of slider. Here, we describe a simulation method for a nonlinear contact model and a nonlinear air bearing spring. The vertical force and moment were calculated using a transient analysis, and applied as an input to a dynamic slider simulation. Simulations were used to investigate the characteristics of the head disk interface in response to shocks of various magnitudes and duration.
