A radio frequency identification (RFID) system for discs such as CDs, DVDs or minidiscs includes a special RFID transponder and antenna configuration. The discs normally include an outer metallized annular zone where information is stored, a central hole, and an inner annular zone between the hole and the outer annular zone. The transponder may be located in the inner annular zone, with antenna elements coupled to the transponder extending in opposite directions part way across the outer annular zone. Multilayer labels with a recess for the transponder chip, and antenna elements formed by conductive material may be employed to apply the RFID assembly to the discs. A monopole or dipole mode of antenna operation, prominently involving the metallized disc layer, results from the antenna configuration, and serves to more than double the range of the system.
