MAGNETIC RECORDING MEDIUM

摘要

PURPOSE:To prevent the durability and antistatic effect of the entitled magnetic recording medium by forming a protective layer containing the fine powder of fluororesin and perfluoroalkyl phosphoric ester on a magnetic layer. CONSTITUTION:A protective layer is formed by dispersing the fine powder of lubricating fluororesin such as resin of tetrafluoroethylene, hexafluoropropylene or trichlorofluoroethylene together with perfluoroalkyl phosphoric ester with surface active and lubricating properties and electric conductivity into an appropriate solvent and applying the dispersoid on a magnetic layer.
