  • Patent number: 6044046
    Abstract: A data carrier in the form of a write-once or rewritable compact disc (CD) includes a circular CD body with an information-carrying layer and a chip integrated in the CD body, the CD further including at least one CD coupling element for noncontact transfer of data between the chip and a data processing device, and of power from the data processing device to the chip. The CD coupling element can be implemented as a coil, an electrostatic coupling surface, or an optical coupling element. For reading out the information applied to the information-carrying layer of the CD, the CD can be inserted into a CD drive. The CD drive has a drive coupling element which, in correspondence with the CD coupling element, is likewise formed as a coil, an electrostatic coupling surface, or an optical coupling element and sends data to the CD coupling element or receives data therefrom.
