Abstract

The present invention relates, amongst other things, to a method for forming a single information-carrying medium (12) composed of two first information-carrying media, utilising a first production line or arrangement (A) for producing a first of two necessary, first information-carrying medium (1), and a second (B), or said first production line or arrangement for producing a second first information-carrying medium (2), wherein each information-carrying medium may display two information-carrying surfaces or layers assigned a microstructure readable only from one side of said medium with the aid of focusing light rays or the like. At least one of said first media (1) consists of two thin discs (15, 9') mouled together (3). At least a first side (15g) of one of these discs (1) has a flat surface structure serving as outer surface for said first medium. A first of said first media (1) is joined to a second of sai first media (2) with said flat surface structures facing away from each other.
