ABSTRACT:
The tape running property of a magnetic recording medium is improved by provision a back layer. This magnetic recording medium comprises a magnetic layer on one side of a non-magnetic support and a back layer on the other side thereof, in which the magnetic layer consists mainly of a ferromagnetic metal powder and a binder and has a coercive force of at least 1000 Oe and a surface roughness of at most 0.03 .mu.m, the ferromagnetic metal powder having a specific surface area of at least 35 m.sup.2 /gr and a saturation magnetization of at least 120 emu/gr, while the back layer has a surface electric resistance of at most 1.times.10.sup.10 .OMEGA. and a surface roughness of at most 0.05 .mu.m.
