A dual sided optical storage medium which comprises a substrate disk having a first information layer readable from one side of the medium through the substrate disk and one or more information layers formed on the non-read side of the first information layer and configured to be read from the other side of the medium.

Dual sided optical storage media and method for making same

Optical recording media configured to deter unauthorized access are described. Methods for manufacturing the optical recording media described above are also presented.

Recording media with features to render media unreadable and method and apparatus for replication of said media

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.

High-density optical recording media and method for making same

A method for manufacturing an optical recording medium includes forming a light-transmitting cover layer over an information layer by depositing a predetermined volume of a liquid resin on the information layer. The method may further include forming a disc rib over an outer periphery of the information bearing side of the substrate, to stop flow of the deposited resin beyond the outer disc periphery. An optical recording medium formed through such a method includes a disc rib delimiting an outer diameter of the light-transmitting cover layer.
