A magnetic recording medium capable of high-density recording and suitable for linear recording/reproducing and the reproduction of signals using a magnetoresistive head is provided. The magnetic recording medium includes a non-magnetic substrate and a magnetic layer having an oblique columnar structure formed on the non-magnetic substrate. The magnetic layer includes a first ferromagnetic metal thin film and a second ferromagnetic metal thin film whose direction of growth of its oblique columnar structure is the opposite of that of the first ferromagnetic metal thin film. Mr.delta, the product of residual magnetization Mr and film thickness delta, satisfies 3 (mA)<=Mr.delta<30 (mA). Thickness d<SUB>1 </SUB>and thickness d<SUB>2 </SUB>of said first and second ferromagnetic metal thin films, respectively, satisfy 40 (nm)<=D<SUB>1</SUB>+d<SUB>2</SUB><=100 (nm) as well as ½<=D<SUB>2</SUB>/d<SUB>1</SUB><1. Coercivity Hc of said magnetic layer satisfies Hc>=100 (kA/m).
