PROBLEM TO BE SOLVED: To increase a recording capacity by heightening density of particles of a magnetic layer of a magnetic recording medium. SOLUTION: A method for manufacturing the magnetic recording medium includes the steps of sputtering at least an underlayer over a substrate layer, where the underlayer is comprised of a Cr-based alloy, and sputtering at least an interlayer over the underlayer, where the interlayer is comprised of a Co-based alloy. The method further includes a step of sputtering at least a overlayer over the interlayer, where the overlayer is comprised of a Co-based alloy. At least one of the underlayer, the interlayer and the overlayer are doped with X, where X is a metal with an oxidation potential of less than -0.6 eV. At least one of the underlayer, the interlayer and the overlayer are reactively sputtered in the presence of oxygen. COPYRIGHT: (C)2006,JPO&NCIPI
