PROBLEM TO BE SOLVED: To provide a processor which can improve availability of a data storage medium. SOLUTION: A removable data storage medium is provided with a processing register means which can register plural authentication data and processing contents corresponding to these authentication data and a processing limitation means which can register, call out or delete the processing contents when coincidence is confirmed between the registered authentication data and the inputted ones. In such a constitution, the processing contents can be executed only when every password is inputted in response to those registered processing contents and thereby the wrong use of a memory card, etc., can be prevented. |
