A magnetic recording medium having plural layers are disclosed. A plastic deformation of an uppermost magnetic layer is from 0.01 to 0.5 .mu.m, and a plastic deformation of the layer other than the uppermost magnetic layer is preferably from 0.01 to 0.6 .mu.m. The uppermost layer preferably has a thickness of less 0.5 .rho.m.
