The copying system includes: a reading section for reading the information from the first recording medium; a detection section for detecting the copying control information within the information read from the first recording medium; a modification section for, if the copying control information represents a condition that “only copying to a second generation copy is permitted”, modifying the copying control information so as to prohibit any further copying; and a writing section for writing information including the modified copying control information, onto the second recording medium.
