Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To easily and inexpensively provide a magnetic forgery of which is difficult to create. SOLUTION: A magnetic head 31 is a high-sensitivity magnetic head and reads a magnetic noise on a magnetic noise read track 71. A control part 21 ciphers it to write it on a noise corresponding data recording track 73.
