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 antenna 231 is provided in an inner peripheral
portion of an optical disc. An IC module 201 connected with
transmission/reception IC 230 including 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.
