Abstract:
An apparatus for storing digital media utilizes an electrically conductive element, which is for reading stored digital media, and multiple electrically conductive resonant circuits as an antenna for radio frequency communications. Each of the resonant circuits is electrically isolated from the other resonant circuits and the electrically conductive element is electrically isolated from each of the resonant circuits. As a result, the apparatus for storing digital media has a relatively wide operating frequency range and a relatively long communications range, which allows worldwide usage in various applications. For example, an optically readable compact disk (CD) utilizes a metal layer configured as a reflective surface for reading stored digital media in the CD, an electrically conductive component that is not in contact with a radio frequency identification (RFID) integrated circuit (IC), and an electrically conductive component that is in contact with the RFID IC, as an antenna for the RFID IC.
