摘要
Provided are a perpendicular magnetic recording medium and a method of manufacturing the same. The perpendicular magnetic recording medium includes: a substrate; a soft magnetic layer formed on the substrate; an underlayer formed on the soft magnetic layer; and a recording layer comprising a plurality of ferromagnetic layers and formed on the underlayer, wherein each of the plurality of ferromagnetic layers has a magnetic anisotropic energy which decreases as distance increases from the underlayer.
