Abstract

Recently, load/unload(L/UL) process is applied to a computer information storage device due to its advantages such as lower power consumption, larger data zone, simpler fabrication of disk for no bumped parking zone, and rarer contact between the slider and media. An analysis of the transient motion for the slider is very important to design an air bearing surface (ABS) of the slider to secure the stable performance of the system. During the L/UL process, however, there are several issues occurred such as contact or collision between slider and media. Sometimes this will cause the system failure. In this study, the dynamics of the slider during the loading process are investigated through a numerical simulation using FEM analysis and experiment.
