ABSTRACT:
An optical information storage system is disclosed which comprises a cathode ray tube having a photochromic fiber optic face plate on which data can be written by appropriate modulation and deflection of the electron beam. The readout function is accomplished by scanning appropriate portions of the phosphor by an electron beam of reduced intensity. Light which passes through the face plate is detected by a photocell.
