In order to achieve a magnetic recording density of 1 Tb/in^2, the spacing is expected to be less than 2-3nm. However, a critical issue in achieving such an ultra-low spacing is the dynamic instability of the head disk interface (HDI).The goal of this research is to clarify the effects of the lubricant materials on slider hysteresis behavior in detail. In this study, the difference in the touchdown velocities was monitored by varying the lubricant film materials of the disks ; further, the correlation between the observed phenomenon and the variation in the experimental parameters was investigated. Considering the obtained experimental results, it was suggested that the variation in the touchdown velocity is due to a variation in the intermolecular forces.
