Abstract

PURPOSE:To improve the durability of entitled magnetic recording medium by forming a protective layer consisting of the fine powder of rubber-like resin and fluororesin on a magnetic layer. CONSTITUTION:A protective layer is formed by applying (e.g. coating) a dispersion of the fine powder of fluororesin having lubricating properties such as resin of tetrafluoroethylene, hexafluoroprophylene and trichlorofluoroethylene in rubber resin such as polyurethane resin, polybutadiene, butadiene-acrylonitrile copolymer, butadiene-styrene copolymer or chloroprene on a magnetic layer.
