The magnetic recording medium has superposed on at least one surface of a non-magnetic support member a magnetic layer possessing a surface shape such that the space-average wavelength (2.alpha.a) is in the range of 15 .mu.m to 30 .mu.m and the surface-average roughness (sRa) in the range of 0.008 .mu.m to 0.025 .mu.m. The magnetic recording medium combines highly satisfactory property of media and magnetic interface with high durability and high reproducing output.
