This paper describes the interactions between flying head sliders and ultra-thin liquid lubricant films. 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 A20H lubricant films were larger than that of Zdol, and the LDV RMS signals for A20H lubricant films became larger than that for Zdol. In addition, the replenishment characteristics of two kinds of ultra-thin liquid lubricant films was studied and discussed.
