Thin film lubricant for advanced tribological performance of storage medium
A lubricant for improving the durability and reliability of recording media used in hard drives is disclosed. The lubricant comprises a perfluoropolyether main chain with a first end attached to a hexa(trifluoromethylphenoxy) cyclotriphosphazene, a second end attached to a bonding enhancer for enhancing bonding between the lubricant and a carbon-containing layer. The bonding enhancer of the lubricant can contain multiple hydroxyl, amide groups, 2,3-dihydroxy-1-propoxyl, acetamide, methacrylate, methyl methacrylate and glycidyl ether. Some bonding enhancers such as methacrylate, methyl methacrylate or glycidyl ether, can be further activated with ultraviolet light.
