Abstract

In one embodiment, the data storage media can comprise: a substrate, a data layer, and a reflective layer disposed between the data layer and the substrate. The substrate can comprise a substrate material selected from the group consisting of polyphenylene ether, blends comprising polyphenylene ether, copolymers comprising polyphenylene ether, mixtures comprising polyphenylene ether, reaction products of a compostion comprising polyphenylene ether, and composites comprising polyphenylene ether. The data layer can comprise a material selected from the group consisting of organic dye and inorganic phase change materials. The storage media can comprise imprinted features. In another embodiment, the first surface data storage media can comprise: a substrate, a reflective layer on a first side of the substrate, and a protective layer disposed on a side of the substrate opposite the first side. The protective layer can comprise silicon dioxide. The first surface data storage media comprises imprinted features.
