Abstract:
An optical disc drive (ODD) includes a radio-frequency identification (RFID) reader. The reader includes a circuit and a coil antenna which has a rotational symmetry with respect to a rotation axis of a motor, shaft and turntable of the ODD. The coil antenna can be secured to a wall of a housing of the ODD or around the motor and/or shaft. The reader can read an RFID tag on an optical disc. The RFID tag includes a circuit and a coil antenna which has a rotational symmetry with respect to the disc. As a result, the RFID tag can be read while the disc is rotating. A magnetic insulating material such as a ferrite polymer composite film is used to magnetically insulate the coil antenna. An authentication code can be read from the RFID tag to control access to content of the optical disc.
