摘要

A device for reversible optical information storage with a polymeric liquid crystalline storage medium, with the storage medium consisting of a macroscopically oriented film of a liquid crystalline polymer that contains photochromic groups, and with the information being stored by local disorientation of the molecules induced by photoisomerization by means of a selectively acting light source.
