ABSTRACT:
A magnetic recording element comprises a polymeric film substrate on which is formed a thin CoNi recording layer. Over the latter is a protective layer of an acrylic copolymer of a perfluoroalkyl methanol ester of acrylic or methacrylic acid, preferably formed by plasma polymerization. The layer is tough, has a low coefficient of friction and protects the magnetic layer against corrosion.
