THERMOPLASTIC SUBSTRATES FOR HOLOGRAPHIC DATA STORAGE MEDIA

摘要

In one embodiment, holographic data storage medium includes a first thermoplastic substrate portion having a thickness less than approximately 2 mm and a second thermoplastic substrate portion having a thickness less than approximately 2 mm. 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.
