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.
