A magnetic recording medium comprising a non-magnetic support, at least one primer layer formed on one surface of the non-magnetic support, a magnetic layer formed on the primer layer, and a backcoat layer formed on the other surface of the non-magnetic support, wherein the magnetic layer has a thickness of 0.30 μm or less and a centerline average surface roughness Ra of 3.2 nm or less, and (P 1 −P 0 ) is 30 nm or less and (P 1 −P 20 ) is 5 nm or less in which P 0 is an averaged height of projections of the magnetic layer, and P 1 , P 2 , - - - and P 20 are heights of the highest, the second highest, - - - and the 20th highest projections of the magnetic layer, respectively. |
