Abstract: A system for storing and retrieving data in the form of unique sets of superimposed angularly oriented optical diffraction gratings, each set of gratings representing a different symbolic character. Each selected character is stored by optically recording the set of gratings associated therewith. Typically, a set of characters representing an address is recorded together with each group of characters representing stored information. Readout is accomplished by comparing quickly the stored sets of characters representing different addresses with an address called for by the system. When the desired address is located, the system reads out all recorded data associated therewith.
