    Abstract: A magnetic data storage medium capable of storing data bits may be configured at least with a magnetic underlayer structure and a recording structure. The recording structure can have at least a first magnetic layer and a second magnetic layer with the first magnetic layer decoupled by being constructed of an alloy of cobalt, platinum, and a platinum group metal element.

    Abstract: Apparatus for recording data and method for making the same. In accordance with some embodiments, a recording layer is supported by a substrate. The recording layer has a granular magnetic recording layer with a first oxide content, a continuous magnetic recording layer with nominally no oxide content, and an oxide gradient layer disposed between the respective granular magnetic recording layer and the continuous magnetic recording layer. The oxide gradient layer has a second oxide content less than the first oxide content of the granular layer.

    Abstract: A stack including a crystallographic orientation interlayer, a magnetic zero layer disposed on the interlayer, and a magnetic recording layer disposed on the magnetic zero layer is disclosed. The magnetic zero layer is non-magnetic or has a saturation magnetic flux density (Bs) less than about 100 emu/cc. The magnetic zero layer and the magnetic layer include grains surrounded by a non-magnetic segregant. The magnetic zero layer provides a coherent interface between the interlayer and the magnetic layer with a lattice mismatch less than about 4%.
