MAGNETIC RECORDING MEDIA WITH SMALL RECORDING GRAIN SIZES, HIGH ASPECT RATIO, AND METHODS OF FABRICATING SAME

原文（中文）

Various apparatuses, systems, methods, and media are disclosed to provide a heat-assisted magnetic recording (HAMR) medium having small recording grain sizes with high aspect ratio. One example magnetic recording medium includes, a substrate, a heat sink layer on the substrate, an underlayer comprising MgO—TiO on the heat sink layer, an interfacial layer comprising TiN on the underlayer, a first nucleation layer on the interfacial layer and comprising FePt—Ag—X, wherein X is an oxide, a second nucleation layer on the first nucleation layer and comprising FePt—Ag—Y, wherein Y is an oxide or a nitride, and a magnetic recording layer on the second nucleation layer. In another example, the TiN is formed as a part of the underlayer rather than in the interfacial layer.
