Abstract: Systems and methods for adding a cap-layer to magnetic recording media are described. In one embodiment, the method may include depositing a magnetic recording layer over a substrate, depositing an interface layer over the magnetic recording layer, and depositing a carbon overcoat layer over the interface layer. In some cases, sputter deposition is used to deposit at least the interface layer. In some cases, oxygen is used as a background gas of the sputter deposition.

Abstract: A stack comprises a substrate, a magnetic recording layer, and a negative thermal expansion layer disposed between the substrate and the magnetic recording layer. The negative thermal expansion layer is configured to reduce thermal profile changes of a surface of the stack opposite the substrate during a heat assisted magnetic recording write operation.
