ABSTRACT:
Information is stored, using a relatively low-power light beam, by redistributing the material in a deformable film. In a disc configuration, positioning of the light beam is achieved by referencing to a previously recorded track. In a document storage and retrieval system the document is scanned with the resultant scanned signal modulating the writing light beam producing a recorded track. This track is optically read with the resultant signal applied to a printer. For optimum utilization of the area, the recording and readout take place at constant velocity.
