PROBLEM TO BE SOLVED: To avoid outputting inadvertently rewritten attribute information to the main body side, in a memory and a memory card mounting attribute information inside it. SOLUTION: At least three sets of attribute information 4, 5 and 6 are provided inside a PC card and a comparator 7 inside the PC card compares attribute information 4, 5 and 6. In the case where at least two sets of attribute information are coincident with each other, the coincident attribute information are outputted to the side of the main body, thereby the possibility of outputting attribute information which is different from original attribute information because of being rewritten inadvertently is reduced compared with the case of having only one set of attribute information inside of the PC card. |
