MAGNETIC RECORDING MEDIUM

摘要

PURPOSE:To enhance the antistatic properties and lubricity by laying a coated film contg. graphite powder and a fluorine-contg. lubricant on the rear side of the substrate. CONSTITUTION:Graphite powder having <=10mum average particle size and a fluorine-contg. lubricant which is liq. or semisolid at ordinary temp. are coated onto the rear side of a substrate having a magnetic layer with a resin binder. The lubricant is perfluoroalkylpolyether, polytrichlorotrifluoroethane or the like.
