PROBLEM TO BE SOLVED: To provide a magnetic card with a universal magnetic head and to make it easily readable by providing a secondary data recording part that is inherent to the magnetic card which is created based on random magnetic data that is formed on a magnetic data recording surface of the magnetic card. SOLUTION: A magnetic data recording surface B2 is laminated and formed on a substrate B1 as a secondary data recording part. While roll-shaped base material C0 is fed in the direction of an arrow, first, non-magnetic material, 1 is randomly attached onto the surface B2 through a nozzle 2. The surface B2 to which the material 1 is attached is magnetized by a magnetic head H. Mangetization of the surface B2 is performed by bringing the head H into contact with the surface B2 by pressure while the material C0 is carried. The material 1 on the surface B2 is removed after it is magnetized by the head H. In this way, magnetic data that is randomly attached is formed on the surface B2 . |
