A magnetic recording medium is formed on a non-magnetic support and a magnetic layer containing a binder and a ferromagnetic powder and having a thickness of 0.7 mum or thinner is formed on the non-magnetic support wherein the surface roughness Ra of the surface of the medium is from 0.5 to 7 nm and the skewness RSK of the surface of the medium is 0.1 or lower.The magnetic recording medium preferably has a nonmagnetic underlayer containing a binder and non-magnetic particles such as carbon black, between the non-magnetic support and the magnetic layer. The magnetic recording medium has excellent electromagnetic recording characteristics and torque characteristics and is suitable for high-density recording.
