Abstract
In this paper, we report slider lubricant interaction phenomena as a function of lubricant thickness and disk velocity on smooth disks. Airbearing vibrations as well as torsional and bending mode vibrations of pico sliders were investigated using a high bandwidth laser Doppler vibrometer (LDV) and a high bandwidth acoustic emission (AE) system.
