Beschreibung
Zusammenfassung:	Perpendicular magnetic recording (PMR) media and methods of fabricating PMR media are described. The PMR media includes, among other layers, a perpendicular magnetic recording layer and a cap layer that are exchange coupled. The magnetic recording layer and the cap layer may be exchange coupled through direct contact, or may be exchange coupled over a coupling layer. In either embodiment, the cap layer is formed from a CoPtCr alloy having a concentration of Cr in the range of about 15-22 at %.
