ABSTRACT:
A disk medium includes a substrate and a designed topography of individually magnetizable features formed on the surface of the substrate. At least a portion of the topography is formed from an etched layer of magnetizable material deposited on the surface of the substrate. An information handling system records information on the disk medium magnetically and reads the recorded information optically or magnetically.
