Substrate patterning in perpendicular storage media

摘要

According to one embodiment, a patterned magnetic storage medium is disclosed herein. The magnetic storage medium includes a pattern formed on a substrate. The pattern includes at least a first and second feature and an edge defined between the first and second features. Additionally, the magnetic storage medium includes a magnetic layer formed on the pattern. The magnetic layer includes grains separated by a non-magnetic segregant boundary. The segregant boundary is positioned above the edge of the pattern.

1. A magnetic storage medium, comprising:
a pattern formed on a substrate, the pattern comprising a first region made from a first material and a second region made from a second material different than the first material, the first region being laterally adjacent the second region; a magnetic layer formed on the pattern, the magnetic layer comprising magnetic grains separated by a non-magnetic segregant boundary, wherein at least one of the magnetic grains is positioned above the first region and at least one of the magnetic grains is positioned above the second region, the non-magnetic segregant boundary being positioned above an edge defined between the first and second regions; wherein the segregant boundary forms a boundary between the magnetic grains.
