Abstract

Abstract Translated from German Die Erfindung betrifft ein Verfahren zur reversiblen, optischen Informationsspeicherung mittels eines flüssigkristallinen Speichermediums, wobei man in einem Film aus einem flüssigkristallinen Seitenkettenpolymeren in einer anisotropen Phase mittels einer lokal wirksamen Wärmequelle in Verbindung mit einem elektrischen, magnetischen oder oberflächenwirksamen Feld über eine lokale Reorientierung die Information einspeichert. The invention relates to a method for reversible, optical information storage by means of a liquid-crystalline storage medium, the information being stored in a film made of a liquid-crystalline side chain polymer in an anisotropic phase by means of a locally active heat source in connection with an electrical, magnetic or surface-active field via a local reorientation .
