Recently, Head-Disk-Interface (HDI) spacing in Hard Disk Drives (HDD) has been decreased to as low as 10nm in order to achieve an ultra-high magnetic recording density. With the increase in magnetic recording density, the HDI spacing of the head has been reduced to such an extent that the effect of the ultra-thin liquid lubricant films on slider dynamics has become more evident. The goal of this research is to clarify the effects of environment on slider hysteresis behavior. In this study, the slider hysteresis behavior was monitored by varying the lubricant film materials of the disk and environmental conditions, by using pump down pressure test. As a result, it was found the effect of temperature on slider hysteresis behavior depends on the lubricant film materials. In addition, it was suggested the variation in the takeoff pressure is caused by a variation in the friction forces between the slider and disk surface.
