摘要:
An optical disc includes an electromagnetic coupling module mounted therein. The electromagnetic coupling module includes a wireless IC chip and a feeder circuit substrate in which a feeder circuit including a resonant circuit having a predetermined resonant frequency is disposed. The electromagnetic coupling module is electromagnetically coupled to a reflective film defining a metal thin film of the optical disc, and the reflective film defines an antenna or radiation pattern of the electromagnetic coupling module.
