ABSTRACT:
A magnetic recording medium is described, which comprises a support having thereon in this order from the support side a substantially nonmagnetic lower layer and a magnetic layer comprising a ferromagnetic powder dispersed in a binder, wherein the magnetic layer has a coercive force of 1,800 Oe or more, central plane average surface roughness (Ra) of 5.0 nm or less, and the magnetic layer contains a diamond fine particle having an average particle size of from 0.10 to 1.0 .mu.m in an amount of from 0.01 to 5% by weight based on the ferromagnetic powder.
