Abstract
The objective of the present invention is to provide an optical disc which solves the problem that search for data recorded on an exchange-type medium such as an optical disc and the like and which allows search for data recorded in an optical disc to be performed with a simple operation. A transmitting/receiving antennais provided in an inner peripheral portion of an optical disc. An IC moduleconnected with transmission/reception ICincluding ID information is formed and embedded into a substrate the optical disc. Thus, an optical disc incorporating an IC module which can be produced on a mass-production basis can be achieved.
