PURPOSE:To obtain a recording medium having a vapor-deposited magnetic metallic film with superior antistatic and lubricating properties by laying a coated film contg. metallic powder and a silicone lubricant or a fluorine-contg. lubricant on the back side of a substrate. CONSTITUTION:Electrically conductive metallic powder such as aluminum powder, copper powder or stainless steel fiber and a silicone lubricant which is liq. or semisolid at ordinary temp. or a fluorine-contg. lubricant which is liq. or semisolid at ordinary temp. are coated onto the back side of a substrate having a vapor-deposited magnetic metallic film with a resin binder. The silicone lubricant is unmodified dimethylpolysiloxane, dimethylpolysiloxane modified with a polar group or the like, and the fluorine-contg. lubricant is perfluoroalkylpolyether, polytrichlorotrifluoroethane or the like. |
