Abstract

We discuss different strategies for optical storage of information in polymeric films. An outline of the existing trends is given. The synthesis and characterization of side-chain azobenzene polyester films for holographic storage of information is described. A compact holographic memory card system based on polarization holography is described. A storage density of greater than 10MB/cm2 has been achieved so far, with a potential increase to 100MB/cm(2) using multiplexing techniques and software correction. Finally the role of surface relief in azobenzene polymers on irradiation with polarized light is mentioned. (C) 2001 Elsevier Science BN. All rights reserved.
