Abstract
Lubricant is applied on the hard disk for both the further reduction of flying height to achieve higher recording densities and maintenance of the reliability of the Hard disk drives. However, the lubricant pick-up phenomena, which is lubricant applied on the disk adsorb on the head by the relative motion between head and disk at ultra-low flying height, causes the flying stability to deteriorate. In this paper, we measured the film thickness of lubricant adsorbed on the slider surface under the condition simulating actual hard disk drive for various flying time and flying height. As a result, we observed that the lubricant film thickness becomes thicker with increasing flying time and reducing flying height.
