Abstract: A perpendicular magnetic recording medium having a dual-layer magnetic film is disclosed. The bottom layer is completely exchange decoupled, and the top layer contains a certain amount of exchange coupling optimized for recording performance. Preferably, the bottom magnetic layer contains stable oxide material (for example, TiO2) and other non-magnetic elements (for example, Cr). A method of manufacturing the media is also disclosed.
