Further, in the recording medium reading / writing apparatus according to the fifth aspect, when the reprint data is encrypted by using the encryption key, the encryption key information is previously stored in the second recording medium. Since the information is recorded, the recording medium such as the IC card can be updated by a method with higher security without giving the information of the encryption key to the reading / writing device (reader / writer) of the recording medium. become.

According to a sixth aspect of the present invention, there is provided a method for reading / writing a recording medium, wherein when the first recording medium is set,
Transfer the authentication data received from the host computer to the recording medium, the data processing unit of the recording medium performs the authentication process,
When the authentication process is successful, the read / write device reads the reproduction data from the first recording medium and transmits it to the host computer. Then, when the second recording medium is set,
The reproduction data is received from the host computer and written in the second recording medium. When the writing of the reproduction data is successful, the first recording medium is collected. This allows
When updating a recording medium such as an IC card from an old card to a new card, a reading / writing device (reader / writer) for the recording medium
It will be possible to safely transfer the data of the old card to the new card without giving the secret information to. Also,
Old cards can be collected and treated as industrial waste. In addition, the person on the spot can confirm whether the updated information is accurate. Furthermore, there is no need to wait for a new card to be issued.

Further, in the recording / reading method of the recording medium according to the seventh aspect, the transcribing data is encrypted by using the encryption key, and when the transcribing data is written in the second recording medium, The data processing unit of the second recording medium performs the verification process of the reprint data using the encryption key, and the first recording medium is collected when the verification result is successful. It is possible to update a recording medium such as an IC card by a method with higher security without giving secret information to the reading / writing device (reader / writer).
