Analysis of slider dynamics induced by various ramp-disk contact situation in hard disk drive

This research investigates to analyze the effect of ramp-disk gap to slider dynamics in operational shock situation. To investigate the effect, simulations is conducted with verified finite element model include various ramp-disk gap. The slider dynamics is more unstable in bigger difference of ramp...

Summary:This research investigates to analyze the effect of ramp-disk gap to slider dynamics in operational shock situation. To investigate the effect, simulations is conducted with verified finite element model include various ramp-disk gap. The slider dynamics is more unstable in bigger difference of ramp-disk gap model.
