Abstract: A holographic data storage medium having an anti-reflective coating is described. The anti-reflective coating can be made to reduce reflectivity for S-polarized light over a wide range of incident angles. Moreover, the anti-reflective coating can be made to have a sufficiently high transmittance for the S-polarized light. The coating may improve performance of the holographic data storage medium, and can facilitate higher storage densities than can be achieved without the coating.

Abstract: In one embodiment, holographic data storage medium includes a first thermoplastic substrate portion having a thickness less than approximately 2 millimeters and a second thermoplastic substrate portion having a thickness less than approximately 2 millimeters. A holographic recording material may be sandwiched between the first and second thermoplastic substrate portions. By making thermoplastic substrate portions sufficiently thin, edge wedge problems can be avoided.
