PROBLEM TO BE SOLVED: To provide a magnetic card whose illegal use by patching or the like is prevented. SOLUTION: A first magnetic recording layer 3 being a track for making a punch hole on a non-magnetic substrate 2 and a second magnetic recording layer 4 being a track for recording data are formed like a stripe, and a shielding layer 5 is formed so that the both magnetic recording layers 3 and 4 can be integrally covered. It is desired that soft magnetic materials whose coercive force is small (for example, 100 oersted or less) are used as the shielding layer. |
