Patent ID: 7978567

Claim:
An optical disc recording and reproducing apparatus for communicating with a noncontact integrated circuit, comprising: a chassis; an external antenna to communicate with an external noncontact integrated circuit located outside the chassis; an internal antenna to communicate with an internal noncontact integrated circuit included in an optical disc loaded in the chassis; a shield to intercept electromagnetic waves generated from the external and internal antennas to prevent interference among the electromagnetic waves during communication; control means for searching for the external noncontact integrated circuit and the internal noncontact integrated circuit; and switching means for changing to a conduction state between the external antenna and the control means to search for the external noncontact integrated circuit, the control means communicating with the external noncontact integrated circuit via the external antenna, and changing to a conduction state between the internal antenna and the control means to search for the internal noncontact integrated circuit, the control means communicating with the internal noncontact integrated circuit via the internal antenna.
