Abstract

PURPOSE: To obtain a magnetic recording medium which has a small surface electric resistance and a small output fluctuation without damaging an electromagnetic conversion characteristic by providing a conductive substance layer including graphite powder between a support material and a magnetic layer.
CONSTITUTION: On a support material such as polyester film, graphite powder of 0.5W1μ particle diameter is included in a conductive substance layer with 20W 40wt%. A material having a good adhesion property to a magnetic layer and the support material such as polyester resin and bridge polyurethane is used as the binder of the conductive substance layer. Thus, the surface resistance of a magnetic tape, etc., is reduced, and faults such as noise caused by adhesion of dirt, etc., dependent upon charging of the surface and drop-out are prevented.
