摘要： A perpendicular magnetic recording medium including an interlayer structure for crystallographically orienting a layer of a hexagonal close-packed (hcp) perpendicular magnetic recording material formed thereon, comprising in overlying sequence from a surface of a magnetically soft underlayer: (1) a first crystalline layer of a material having a first lattice parameter and a strong preferred growth orientation; (2) a second crystalline layer of a material having a second lattice parameter and the same strong preferred growth orientation as the first crystalline layer; and (3) a third crystalline layer of an hcp material, having a [0002] lattice parameter similar to or different from that of the second lattice parameter of the second crystalline layer and a strong preferred growth orientation, wherein: the second crystalline layer has a lower interfacial energy with the first crystalline layer and a higher interfacial energy with the third crystalline layer, owing to a lower surface energy of the first crystalline layer and a higher surface energy of the second crystalline layer.

摘要： An apparatus and method are provided for improving perpendicular magnetic recording media. The present invention provides media, and a method of fabricating media in a cost-effective manner, with a reduced ruthenium (Ru) content interlayer structure, while meeting media performance requirements. A perpendicular magnetic recording medium is provided comprising a non-magnetic substrate having a surface, and a layer stack situated on the substrate surface. The layer stack comprises, in overlying sequence from the substrate surface a magnetically soft underlayer; an amorphous or crystalline, non-magnetic seed layer; an interlayer structure for crystallographically orienting a layer of a perpendicular magnetic recording material situated on the underlayer; and at least one crystallographically oriented, magnetically hard, perpendicular magnetic recording layer situated on the interlayer structure. The interlayer structure is a stacked structure comprising, in overlying sequence: a chromium alloy situated on the seed layer; and an upper interlayer situated on the chromium alloy.
