We report high-contrast storage of 64-kbit digital data pages in a photorefractive polymer material. Single-page writing, reading, and erasing operations were demonstrated with a dual-function-dopant polymeric material having a dark lifetime of several days. Data were reconstructed without error by use of several simple readout algorithms.
