Abstract (en)
[origin: WO0163604A1] A data memory (1) has an optical information support which has a polymer film (11) that is wound into several layers (10) in a spiral shape. Information from a preselected layer (10) of the polymer film can be read out through said polymer film and optionally, written into a preselected layer of the polymer film (10). A lacquer layer (12) which is configured in the form of an adhesion layer is situated between adjacent polymer film layers (10).
