Abstract
A radio frequency transponder for use with a disc, such as a CD or DVD has an antenna formed by depositing a conductive solution on a surface of disc outside at adjacent to its outer periphery outside of the disc storage area to yield at least one conductive region. A transponder circuit is coupled to the antenna for supplying an RF signal to the antenna in response to a signal received from the antenna.
Claims7
A method of providing a radio frequency (RF) transponder circuit on a medium containing a storage area with metallization, comprising the steps of:
- forming an antenna on the medium by depositing a conductive solution on a surface of a non-metallized region of the medium both outside of the storage area and adjacent to an outermost periphery of the medium to yield at least one conductive region, wherein the forming is performed in conjunction with printing, on said surface, at least one of artwork and descriptive indicia;
- and
- coupling a transponder circuit to the antenna for supplying an RF signal to the antenna in response to a signal received from the antenna.
