Abstract
A data storage medium includes a substrate, and a plurality of spaced-apart discrete data storage tracks supported by the substrate. The data storage medium also includes magnetic flux sinking material between the discrete data storage tracks and over the substrate. As an alternative to the magnetic flux sinking material, plasmonic material may be included between the discrete data storage tracks and over the substrate.
