摘要：
A magnetic recording medium with tuned exchange coupling comprises: (a) a non-magnetic substrate having a surface; and (b) a stack of thin film layers on the substrate surface, including: (i) a compositionally segregated, exchange decoupled magnetic layer with substantially non-magnetic grain boundaries; and (ii) an exchange coupled magnetic layer adjacent to and in direct contact with the exchange decoupled magnetic layer.
