PROBLEM TO BE SOLVED: To provide a magnetic processor capable of preventing a magnetic recording medium from being illegally used, miniaturizing a device and fast processing the magnetic recording medium and to provide a magnetic recording medium that is processed by the device. SOLUTION: This magnetic processor has a carrying mechanism carrying a magnetic card, a head for reading which reads magnetic data written on a magnetic track of the magnetic card and a head for writing which writes magnetic data on a magnetic track of the magnetic card. The magnetic track of the magnetic card is made of MB magnetic material obtained by mixing B magnetic material that has relatively low coercive force and is capable of rewriting data with M magnetic material whose coercive force rises extremely once data is written and is capable of one time writing. Also, magnetic data read by the head for reading are detected as a waveform having double peaks. |
