Abstract

The information carrier (1) contains a storage unit (9), an integrated circuit (10) and a first and a second coupling element (31, 32). Said coupling elements (31, 32) are intermediate in the transfer of data and energy from a base station (50) to the integrated circuit (10) and vice versa. Between the base station (50) and said coupling elements (31, 32) the transfer of data and energy is contactless, and preferably by capacitive coupling. Between at least the first (31) of and preferably both of the coupling elements (31, 32) data and energy are transferred by means of capacitive coupling. The base station (50) is preferably incorporated in an apparatus (40) further containing the reading device (60) of the storage unit (9). To facilitate the capacitive coupling, the base station (50) contains a first and a second capacitor plate (54, 55). The information carrier (1) and the apparatus (40) with the base station (50) containing said capacitor plates (54, 55) together constitute the system, which is suitable for copy protection of the information on the storage unit (9).

Claims

1-13. -13. (canceled)

14. A substrate (21) provided with a layer of conductive ink (22) and a glue layer (23), characterized in that the substrate (21) is suitable for fastening to a disc-shaped information carrier (1) provided with a hole (5) centrally situated in the information carrier (1) and having a diameter, and the substrate (21) is provided with a hole (25) having a diameter which is at least equal to the diameter of the hole (5) in the information carrier (1).

15. The substrate of claim 14 wherein the substrate is disk-shaped.

16. The substrate of claim 14 wherein the layer of conductive ink includes an inner ring of conductive ink and an outer ring of conductive ink that is separated from the inner ring, the inner and outer rings each being concentric about the hole in the substrate.
