Abstract
Official abstract text for this publication.
A perpendicular magnetic recording medium, comprising: a substrate; a buffer layer deposited in a first orientation on top of the substrate; an underlayer deposited in a second orientation on top of the buffer layer, the underlayer comprising an electrically conductive oxide; and a magnetic recording layer deposited on top of the underlayer and having an axis of magnetic anisotropy substantially perpendicular to the surface thereof.
First claim
Opening claim text (preview).
What is claimed is: 1. A perpendicular magnetic recording medium, comprising: a substrate; a buffer layer deposited in a first orientation on top of the substrate; an underlayer deposited in a second orientation on top of the buffer layer, the underlayer comprising an electrically conductive oxide of Mg with one or more of Ti, Zr and Hf, the oxide comprising between 5 and 35 atomic percent Mg; and a magnetic recording layer deposited on top of the underlayer and having an ax…
