摘要： A magnetic recording medium, the order of layers in which is the substrate, the soft underlayer, the seedlayer, the 1st RuCrx-containing interlayer, the 2nd RuCrx-containing interlayer and the magnetic recording layer with preferably a oxides or nitrides-containing magnetic layer comprising grains, is disclosed. High-chromium ruthenium-chromium alloy used as inter layers significantly enhances coercivity and SMNR preferably due to the improved lattice match between RuCr inter layers and CoPt-based magnetic recording layers, and the surface energy of RuCr layers contributes to the performance improvement with the high-chromium addition into Ru inter layers.

The method preferably entails obtaining a non-magnetic substrate, heating the substrate at a temperature T1 that is greater than 150° C., forming a first layer with body-centered cubic atomic structure and with a preferred growth orientation, cooling the substrate to a temperature T2 and forming a second layer comprising a magnetic oxide-containing granular magnetic layer with a hexagonal close packed atomic structure and with a preferred growth orientation. The magnetic oxide-containing granular magnetic layer contains magnetic crystal grains that are substantially isolated by an inter-granular region comprising a non-magnetic substance, wherein the non-magnetic substance is preferably an oxide-containing material.
