Magnetic recording medium

A magnetic recording medium comprising a support, a magnetic layer provided on one side of said support, and a backcoat provided on the other side of said support, wherein said backcoat comprises a binder resin and a non-magnetic powder, said binder resin being selected from the group consisting of polyurethane resin and nitrocellulose, said non-magnetic powder contained in an amount from 4-60% by weight of the total amount of components of said backcoat and having an average grain size of range of from 0.5 .mu.m to 2 .mu.m and a maximum grain size of not more than 5 .mu.m and wherein the amount of non-magnetic powder having a grain size of more than 3 .mu.m is less than 20% by weight of the total amount of said non-magnetic powder, said backcoat further containing an isocyanate as a hardener and said non-magnetic powder grains have an average center-line-average roughness (R.sub.a) of 0.015 .mu.m to 0.04 .mu.m.
