A system and method for improving the durability and reliability of
recording media used in hard drives is disclosed. A protective overcoat
made of diamond like carbon (DLC) is first deposited over a magnetic
layer. A lubricant layer, typically containing Moresco lubricant or a
perfluoropolyether (PFPE), is then deposited over the protective
overcoat. Finally, the lubricant layer is exposed to ultraviolet (UV)
light for a period of time.
