摘要：
A perpendicular magnetic recording medium is provided. The perpendicular magnetic recording medium has an underlayer for leading perpendicular orientation of a perpendicular magnetic recording layer, stacked between a substrate and the perpendicular magnetic recording layer, and thickness of the perpendicular magnetic recording layer is controlled within the range of 5-40 nm to have a negative nucleation field.
