This paper describes the interactions between flying head sliders and ultra-thin liquid lubricant films. We investigated the influence of the bonded ratio as well as de-wetting of the lubricant film on the slider dynamics. Zdol2000S was used for the lubricant. The dynamics of sliders was monitored using Laser Doppler Vibrometer (LDV) and Acoustic Emission (AE). The slider hysteresis behavior of touch-down and take-off processes was investigated as a function of the disk velocity. As a result, it is found that the difference between touch-down velocity and take-off velocity of high bonded ratio lubricant films were larger than that of low bonded ratio ones. And the LDV RMS signals for high bonded ratio lubricant films became larger than that for low bonded ratio ones. In addition, it is found that de-wetting of a lubricant film affects the slider dynamics.
