In a perpendicular magnetic recording medium, a multilayered underlayer including a first metal underlayer, a second metal underlayer having no solid solution properties with respect to the first metal underlayer and having a hole, and a third metal underlayer having solid solution properties with respect to the first metal underlayer and having no solid solution properties with respect to the second metal underlayer is formed on a substrate, and a magnetic recording layer is formed on the multilayered underlayer.
