Abstract
The present invention provides an optical disc recording and reproducing apparatus having a function of communicating with a noncontact IC. The apparatus includes a chassis, an external antenna arranged for communication with a noncontact IC outside the chassis, an internal antenna arranged for communication with a noncontact IC included in an optical disc loaded in the chassis, a control section performing a search operation of searching for the noncontact IC outside the chassis and the noncontact IC in the optical disc, and a switching section changing conduction state between the external antenna and the control section and that between the internal antenna and the control section under the control of the control section.
