ABSTRACT:
An information-storage media is provided that includes:(a) a substrate disk312having first and second opposing surfaces;(b) a first interface layer304on the first surface, the first interface layer having a first thickness;(c) a second interface layer308on the second surface, the second interface layer having a second thickness, wherein the first and second interface layers have a different chemical composition than the substrate disk; and(d) an information-storage layer412adjacent to one or both of the interface layers.The first and second thicknesses are different to provide an unequal stress distribution across the cross-section of the media.
