Intermediate tri-layer structure for perpendicular recording media

An improved structure for the construction of perpendicular recording media is disclosed. The structure includes a tri-layer IML resident between a soft under layer CoTaZr film and a CoPtCr-SiO2 magnetic media. In an embodiment, the tri-layer comprises a RuxCr1−x layer over dual nucleation layers of...

Summary:An improved structure for the construction of perpendicular recording media is disclosed. The structure includes a tri-layer IML resident between a soft under layer CoTaZr film and a CoPtCr-SiO2 magnetic media. In an embodiment, the tri-layer comprises a RuxCr1−x layer over dual nucleation layers of Ni-Fe and Ni-Fe-Cr. The tri-layer replaces the typical Ru and Ni-Fe intermediate layers of the prior art, resulting in considerable improvement in lattice matching between the Ru containing intermediate layer and the CoPtCr-SiO2 magnetic media, further resulting in improved magnetic media performance.
