Abstract
An apparatus for impeding counterfeiting, impeding stealing and managing optical disk stock is described. The radio frequency identification (RFID) system is applied in an apparatus for impeding counterfeiting, impeding stealing, and managing optical disk stock. The apparatus has a disc, a RFID chip and an antenna. The disc has a first annular area, a second annular area and a third annular area. The second annular area is a data recording area with a metal recording layer. The first annular area and the third annular area both are areas without data. The RFID chip is embedded in the disc and the antenna connects to the RFID chip. The RFID chip and the antenna are located in the third annular area. The apparatus further has a foldable matching circuit to increase an inductance of the antenna and shorten the length of the antenna with even poles.
