Abstract: A three dimensional magnetic recording media can consist of a coupling layer disposed between first and second vertically stacked recording layers. The coupling layer can provide exchange or antiferromagnetic coupling and allow the respective recording layers to be individually heat selected to different first and second coupling strengths through application of heat from a heat source.

Abstract: Various magnetic stack embodiments may be constructed with a soft magnetic underlayer (SUL) having a first thickness disposed between a substrate and a magnetic recording layer. A heatsink may have a second thickness and be disposed between the SUL and the magnetic recording layer. The first and second thicknesses may each be tuned to provide predetermined thermal conductivity and magnetic permeability throughout the data media.

Abstract: An apparatus includes a non-metallic interlayer between a magnetic data storage layer and a heat sink layer, wherein interface thermal resistance between the interlayer and the heat sink layer is capable of reducing heat flow between the heat sink layer and the magnetic data storage layer.

Abstract: A thin film structure in the form of, for example, a magnetic recording medium having a deceased C-axis distribution is provided. The structure includes a substrate having a first surface and a second surface non-parallel to the first surface, a seed layer overlying the first surface and the second surface of the substrate and a magnetic material layer on the seed layer. The magnetic material layer has a C-axis tilted with respect to an axis perpendicular to the magnetic material layer, i.e., a surface normal of the magnetic material layer. The seed layer has a columnar structure oriented generally perpendicular to either the first surface or the second surface of the substrate. The columnar structure of the seed layer acts as a template to epitaxial growth.

Abstract: A thin film structure that includes a hard magnetic recording layer, a soft magnetic underlayer and an intermediate layer between the hard magnetic recording layer and the soft magnetic underlayer is disclosed. The intermediate layer comprises a soft magnetic interlayer, and a non-magnetic interlayer between the soft magnetic interlayer and the hard magnetic recording layer. The thin film structure can be a recording medium. The soft magnetic interlayer can be crystalline.

Abstract: A thin film structure, such as a magnetic recording media, having a magnetic layer and a stress-effecting layer is disclosed. The stress-effecting layer induces a magneto-elastic anisotropy in the magnetic layer. The stress-effecting layer can be activated by the application of an external stress and/or strain. The induced magneto-elastic anisotropy can transiently achieve and/or enhance a tilt angle of the medium. The medium can be a perpendicular magnetic recording medium, a longitudinal magnetic recording medium and/or a tilted magnetic recording medium. The magnetic recording media is suitable for use with a data storage system, such as a HAMR data storage system.

Abstract: A deposition system including a shadow mask with one or more apertures, and a method are described for oblique deposition of tilted thin films with azimuthal symmetry. The deposition system is used with physical vapor deposition processes to provide improved control of the angle of incidents of the flux combined with rotation of the substrate to create titled thin films with improved properties compared to conventional oblique deposition techniques.
