Abstract
A thin film magnetic according medium with enhanced coercivity is provided. The magnetic recording medium comprises a non-magnetic substrate having a surface and a layer stack atop the substrate surface. The layer stack comprises a magnetic recording layer and a dual intermediate layer structure below the magnetic recording layer comprising a base layer and a non-magnetic layer between the base layer and the magnetic recording layer. The non-magnetic layer has a thickness less than that necessary for RKKY coupling between the base layer and the magnetic recording layer, and provides the medium with increased coercivity.
