OPTICAL MEMORY WITH STORAGE IN THREE DIMENSIONS

A data recording and read-out apparatus and method in which a ferroelectric ceramic substrate is remanently polarized to store information. Upon being illuminated, the substrate produces a photovoltaic voltage, which is detected to effect read-out. A disk of ferroelectric ceramic material to which i...
