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.

摘要： A perpendicular magnetic recording layer may include a hard granular layer, an exchange break layer formed on the hard granular layer, and a soft granular layer formed on the exchange break layer. In some embodiments, the exchange break layer may consist essentially of ruthenium. In some embodiments, the perpendicular magnetic recording layer may include n magnetic layers and n−1 exchange break layers, where n is greater than or equal to three, and where the n−1 exchange break layers alternate with the n magnetic layers in the magnetic recording layer.
