This invention teaches a methodology and an optical apparatus that provides long-term, archival storage using a chemically stable, high-resolution, photosensitive emulsion, such as silver halide, for the long-term, archival storage and retrieval of data, images and text. Multiple state data substantially increasing data density is stored as vertical diffraction gratings in the archival photosensitive emulsion. The data can be read out in parallel, substantially increasing retrieval speeds beyond that of current optical and magnetic techniques.

Write once read forever archival data storage

The invention combines several techniques applying high-resolution photosensitive emulsions for the long-term, archival storage of data, images and text. Data is stored as vertical interference patterns of multiple frequencies in a photographic emulsion. Read-out of the stored data uses a precision mechanism to locate and decode stored data.

Wave-based optical data storage

The invention relates to imaging devices and methods, pertinent to electromagnetic energy in visual and other spectra, to capture and reproduce substantially all image information in a relevant spectrum through all-electronic sensors and electronic computation means.
