    摘要： An apparatus includes a substrate and a magnetic layer coupled to the substrate. The magnetic layer includes an alloy that has magnetic hardness that is a function of the degree of chemical ordering of the alloy. The degree of chemical ordering of the alloy in a first portion of the magnetic layer is greater than the degree of chemical ordering of the alloy in a second portion of the magnetic layer, and the first portion of the magnetic layer is closer to the substrate than the second portion of the magnetic layer.

    摘要： Magnetic layers are described that include the use of magnetic grains and non-magnetic grain boundaries with hybrid additives. Hybrid additives include the use of at least two different additives in the composition of the grain boundaries of a magnetic layer in magnetic recording media. The use of hybrid additives in the grain boundaries results in improved recording media. Methods for forming magnetic layers and magnetic recording media with the hybrid additive grain boundaries are also described.

    摘要： A perpendicular magnetic media includes a substrate, a patterned template, a seed layer and a magnetic layer. The patterned template is formed on the substrate and includes a plurality of growth sites that are evenly spaced apart from each other. The seed layer is formed over the patterned template and the exposed areas of the substrate. Magnetic material is sputter deposited onto the seed layer with one grain of the magnetic material nucleated over each of the growth sites. The grain size distribution of the magnetic material is reduced by controlling the locations of the growth sites which optimizes the performance of the perpendicular magnetic media.
