ABSTRACT:
Methods and apparatii are described for information storage in photoconductive film of single layer composition by irradiation of memory elements simultaneously with application of an electric field. Information is stored as trapped charge accumulations in the film when the irradiation is removed, but trapped charge can be released by subsequent irradiation. Repeated information storage, followed by erasure, returns the films to their original state without degradation.
