用されることのないようにすることを目的とする。Conventionally, a thin data receiving / transmitting recording medium such as a non-contact IC tag has an antenna made of a conductive layer inside and an IC chip mounted on a terminal portion of the antenna. The data is transmitted and received based on a specific communication standard, so compared to writing on a recording medium such as a conventional magnetic disk or optical disk, a single data transmission / reception recording body is used. Has very high security and good reliability in protecting data. However, once the security of the entire system using the non-contact data transmission / reception recording medium is broken, it becomes possible to rewrite the recording data of the data transmission / reception recording medium. At present, there is no system that disables the data recording / reception recording medium after one use, and measures have been taken to prevent the use of the data recording / reception recording medium obtained by unauthorized acquisition and rewriting of data. I didn't. In view of the above circumstances, an object of the present invention is to make it possible to easily disable a data receiving / transmitting recording medium when necessary, and to use a data receiving / transmitting recording body in which data has been illegally rewritten. The purpose is not to be.

That is, in the present invention, a high-frequency electromagnetic wave is applied to the data transmission / reception recording medium. If the high-frequency electromagnetic wave is applied to the data reception / transmission recording medium, the data reception / transmission recording medium is more exposed than the conductive layer on the substrate. Since the IC chip is mounted on the terminals of a plurality of loop-shaped antennas, a discharge occurs between the antennas, causing an overcurrent state at the discharge site, and the antenna is destroyed and cannot be used. Becomes Specifically, the temperature of the place where the overcurrent has occurred becomes high, and the binder, which is one of the components constituting the conductive layer, is burnt and the conductive layer is in a disconnected state. In the antenna, a thinner portion is more likely to generate a discharge, and can be easily broken. In addition, the connection portion between the IC chip and the antenna can be broken by high-frequency electromagnetic wave irradiation. The frequency range of the radiated electromagnetic wave is 1 to 10 GHz, preferably 2 to 7 GHz. FIG. 1 shows an example of antenna destruction, in which a data transmission / reception recording medium 1 is continuously sent to an electromagnetic wave irradiating device 2 and the data reception / transmission recording medium 2 is irradiated with an electromagnetic wave 3. Antenna destruction can be performed.

GHz). When the formed conductive pattern was irradiated with high-frequency electromagnetic waves using the above-described apparatus, it was found that a thinner pattern was more susceptible to destruction. Further, when high-frequency electromagnetic waves were irradiated with the antenna pattern on which the IC chip was mounted, it was found that the IC chip mounted portion was destroyed.
Then, it was found that the antenna pattern was similarly destroyed even with a conductive pattern formed by sealing with a hot melt adhesive.

実用性に優れた効果を奏するものである。As described above, according to the method for destroying an antenna in a data transmission / reception recording medium of the present invention, an IC chip is mounted on a terminal portion of an antenna made of a conductive layer on a substrate, and data can be transferred in a non-contact manner. The present invention is characterized in that a high-frequency electromagnetic wave is applied to a data transmission / reception recording medium provided for transmission / reception and data recording. In this way, the data receiving / transmitting recording medium can be made unusable by a very simple operation of irradiating high-frequency electromagnetic waves, and thus, by rewriting the new data by performing antenna destruction after proper use. Cannot be performed, and the reuse of illegally obtained data receiving / transmitting recorded materials can be prevented beforehand.
The effect is excellent in practicality.
