Recording medium and information processing device for managing read-in information

摘要

A recording medium 10 is provided with a read only memory 12 having a program recorded therein and a non-volatile memory 13 in which a virgin code is written when it is under non-use state. When an information processing device 50 detects the virgin code, it writes the ID code thereof. The information processing device 50 does not read out any program from a recording medium which is not the recording medium 10 in which the ID code thereof is recorded. Therefore, the program can be executed only by the information processing device which is registered in the recording medium 10, whereby the association between the recording medium and the specific information processing device can be strengthened.
