Abstract
Head disk interface (HDI)system assisted by vapor Perfluoropolyether (PFPE)lubrication was discussed in this paper. PFPE on magnetic disks are widely used as the lubricants for hard disk drives to prevent from the wear at the head disk interface (HDI). The thickness of lubricant changes due to the spin-off and wear by the contact between head and disk. In this study, we confirmed that vapor lubrication replenishes the depletion of lubricant film and the adsorbed lubricant thickness saturated with disk rotation time.
