Abstract

Abstract Translated from German Vorrichtung zur reversiblen optischen Informationsspeicherung unter Verwendung von polymeren Flüssig­kristallen als Speichermedium, wobei die Vorrichtung einen orientierten Film aus einem flüssigkristallinen Hauptkettenpolymeren als Speicher­medium enthält und eingerichtet ist, um mittels einer Wärmequelle das Speichermedium zur Einspeicherung lokal aufzuheizen und über eine lokale Variation der Molekülorientierung die Information einzu­speichern. Device for reversible optical information storage using polymeric liquid crystals as the storage medium, the device containing an oriented film of a liquid-crystalline main chain polymer as the storage medium and being set up to locally heat the storage medium for storage by means of a heat source and to store the information via a local variation of the molecular orientation .
