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