Paper Abstract

We review recent progress made towards commercializable read-write, fast-access holographic data storage. This includes a recent demonstration of high areal density holographic storage, systems architectures for extending this high density to high capacity using phase-conjugate readout, and recent experimental progress along these lines. Other topics include using signal processing to relieve alignment and distortion constraints, optical elements for improving beam uniformity, and most importantly, requirements and prospects for improved photorefractive materials for two-color, gated nonvolatile holographic storage.
