LUBRICANTS COMPRISING PFPE TERMINATED WITH BENZENE OR FUNCTIONAL BENZENE END GROUPS FOR MAGNETIC RECORDING MEDIA STRUCTURE

摘要

A novel lubricant comprising a perfluoropoyether (PFPE) molecule terminated with a benzene molecule or a functional benzene molecule for a magnetic recording media structure is disclosed. The magnetic recording media structure includes a substrate, a magnetic recording layer for recording information disposed over the substrate, a protective overcoat layer for protecting the magnetic recording layer disposed over the magnetic recording layer, and a lubricant layer disposed over the protective overcoat layer and comprising a perfluoropoyether (PFPE) molecule terminated with a benzene molecule or a functional benzene molecule.
