Abstract
A petabyte diffractive storage system stores information on a diffractive storage tape. A light component generates a large reference beam to cover the plurality of points of the diffractive storage tape so as to simultaneously interfere with the plurality of object beams creating a plurality of packets of information at the plurality of points. Also disclosed is a terabyte diffractive storage that system reads information from a diffractice storage disk having a plurality of tracks. A plurality of micro-mirrors directs the read beam to one of said plurality of tracks.
