ABSTRACT:
The invention concerns a process for reversible optical information storage by means of a liquid crystal storage medium, whereby the information is stored in a firm of a liquid crystal side chain polymer in an anisotropic phase by means of locally acting heat source in combination with an electric, magnetic or surfaces active field, through local reorientation.
