Perpendicular magnetic recording media with an amorphous underlayer

Image Number 3 for United States Patent #6921585.

Perpendicular magnetic media are described for use in magnetic recording and data storage. For example, a magnetic medium may include a substrate, an amorphous underlayer formed over the substrate, a seed layer formed over the amorphous underlayer, and a multi-layered magnetic stack formed over the seed layer. In this manner, high perpendicular magnetic anisotropy can be achieved and storage densities can be increased.
