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 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.

1-3. (canceled)
A wireless communication system comprising a device having an IC for transmitting/receiving radio waves and a remote control device for wirelessly communicating with the device having the IC,
- wherein the IC includes:
- a receiving section for receiving the radio waves;
- a detection section for detecting the received radio waves and outputting electric power and a first signal;
- a power accumulation section for accumulating the electric power output from the detection section;
- an ID information storage section for storing ID information for identifying the device having the IC;
- a signal generation section for outputting, in response to the first signal output from the detection section, a second signal including the ID information using the electric power accumulated in the power accumulation section;
- and
- a transmitting section for transmitting the second signal output from the signal generation section,
- wherein the remote control device includes:
- a transmitting section for transmitting radio waves including the first signal to the device having the IC;
- a receiving section for receiving the second signal from the device having the IC;
- and
- an ID reproduction section for reproducing the ID information based on the second signal received by the receiving section.
