Abstract
The present disclosure provides a high-density optical storage medium which comprises a substrate structure having a thickness of 1.0 mm or more and including one or more information layers, a high-density information layer bonded via an adhesive spacer layer to the substrate structure, and a cover layer over the high-density information layer. The high-density information layer can be formed by transferring a reflective film to the substrate structure from a substrate formed of a material (such as polymethyl methacrylate) that does not bond well with the reflective film.
