Abstract

This paper reports results of experimental investigations into slider-disk interaction and slider vibration in nanometer spaced head-disk interface. The investigations were based on an slider-disk interface (HDI) configuration which retains the tribological features of the interface formed by the functional head slider and disk media but make the optical monitoring and quantitative measuring of the slider disk spacing possible. The effects of the lubricant and its thickness on the HDI dynamics were also studied. The results indicate that the slider vibration is dependent not only on slider air-bearing surface design but also strongly on lubricant and other interface conditions
