Abstract
A magnetic recording medium including a magnetic layer formed on a plastic base and having perpendicular magnetic anisotropy suited for perpendicular magnetization, has a back coating formed on the rear side of the base opposite the magnetic side. The back coating is a thermoset coating cured from a thermosetting composition or a radiation-cured coating cured from radiation-curable composition containing at least one component having at least one acrylic, maleic, or allylic double bond. The back coating has an asperity in the range of 0.04 to 0.6 .mu.m. By suitably selecting the asperity the running quality and output profile are improved.
