A magnetic recording medium for use in reproduction with an MR head, which comprises: a non-magnetic substrate; a non-magnetic layer including a binder resin having dispersed therein a non-magnetic powder on the non-magnetic substrate; and a magnetic layer on the non-magnetic layer, wherein the magnetic layer is obtained by applying a magnetic coating material on the applied, dried and cured non-magnetic layer, the magnetic layer includes a metal magnetic powder with a mean major axis length of from 0.03 to 0.08 mum, and a saturation magnetization sigmas of from 100 to 130 Am<2>/kg, and the center line mean roughness Ra of the magnetic layer surface is 5 nm or less.
