Embodiment Construction

[0059] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0060] (composition of disc)

[0061] Next, an embodiment in which the present invention is applied to a disc-shaped recording medium will be described.

[0062] FIG. 1 shows an example of the structure of an optical disc 1 according to an embodiment of the present invention.

[0063] A transmitting antenna 2 and a receiving antenna 3 are provided on the inner periphery of the optical disc 1 . The transmitting antenna 2 and the receiving antenna 3 are formed along the circumferential direction of the optical disc 1 . In this example, both the transmitting antenna 2 and the receiving antenna 3 are dipole antennas.

[0064] On the inner peripheral portion of the optical disc 1, a transceiver IC 4 connected to the transmitting antenna 2 and the receiving antenna 3 is further provided. The transceiver IC 4 receives radio waves via the receiving antenna 3 and transmits r...

Abstract

The purpose of the present invention is to resolve the problem that data recorded in an exchange type media, such as a compact disc, are difficult to be retrieved, and provide a compact disc which can retrieve data recorded in the compact disc by a simple operation. A transceiving antenna (231) is arranged on the inner circumference of the compact disc to form an IC module (201) connected with a transceiving IC (230) with ID information, and is embedded into the underlayer of the compact disc. Consequently, the compact disc with the built-in IC module and good batch productivity can be obtained.

Description

technical field [0001] The invention relates to an optical disc and a remote control device. Background technique [0002] In recent years, the importance of ID information is increasing. Experiments are also underway to embed ICs containing ID information in various products. It is expected that this application will be further developed in the future (for example, Patent Document 1). In the past, no method has been proposed for physically exploring an optical disc in which an IC including ID information is provided on a removable optical disc. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2002-83482. [0004] Removable optical discs take advantage of their removable properties to record content and then distribute it. Therefore, there is a need for a method of retrieving content that has been recorded on a removable optical disc. An object of the present invention is to provide an optical disc and a remote control device capable of searching c...
