Fast duplication of diffractive storage device for mass production

摘要

A master memory device that stores a plurality of pages of information. An unexposed memory device ( 190 ) is adjacent to the master memory device ( 180 ). The unexposed memory device and the master memory device are separated by a gap. An aperture unit ( 130 ) is disposed in the gap. The aperture has a plurality of aperture openings. Each opening corresponds, in size, to an individual page constitutes of a column with specific multiplexing angles of memory in the master memory device. The aperture unit is located across a face of the master memory device such that the openings correspond to selected ones of the pages of information. A light source ( 120 ) generates a beam that transfers memory data from the master memory device to the unexposed memory device.
