ABSTRACT:
A magnetic recording medium including a nonmagnetic support, a lower nonmagnetic layer, and an upper magnetic layer. The nonmagnetic support has a surface. The lower nonmagnetic layer is provided on the surface of the nonmagnetic support. The lower nonmagnetic layer is formed by coating a nonmagnetic coating solution including carbon and a binder. The nonmagnetic coating solution has thixotropy. The upper magnetic layer is provided on the lower nonmagnetic layer and has an average thickness of at most 0.3 .mu.m. The upper magnetic layer includes ferromagnetic powder. A surface roughness of the surface of the nonmagnetic support is limited according to a degree of the thixotropy of the nonmagnetic coating solution.
