Abstract

PURPOSE:To inhibit reproduction of a recording medium for a designated number of permissible times, by checking discriminating information and the number of times of copying at each copy instruction, in an information processor permitting reproduction. CONSTITUTION:At each time when a copy indication is given to an information processor H, if the copy of a recording medium S given with the discrimination information X specifying the attribute of the software to be copied is permitted is determined by comparing and discriminating the information Y in a corresponding table T for the discriminating information X and the copy permission number of times N, and the number of times of copies of the recording medium S is limited for permission.
