<p>A three-dimensional information carrier is presented. The information carrier comprises at least two information layers that are of different types with respect to recording data therein. At least one of the at least two information layers is adapted for recording data therein, and at least one of the at least two information layers comprises a substantially fluorescent material. The fluorescent material is capable of producing output fluorescent radiation, when interacting with a predetermined incident radiation.</p> |
