摘要：PURPOSE:To securely prevent the forgery of a card by setting the coil of a magnetic head for fixed data reading to be a capacity in which a read current is set to be a limit. CONSTITUTION:The detection coil of an allowable current more than several hundreds mA is used for the detection coil 161 of a magnetic head for variable data MD 2 so that the read current and a write current can be flowed. Since the detection coil 161 of the magnetic head for fixed data MD 1' is used only for reading, the detection coil for the allowable current more than the read current and less than the write current is used so that the read current of about several mA securely flows but disconnection is executed when the write current less than several hundreds mA flows. When a write part 30 for forgery is connected to the magnetic head for fixed data MD 1' and information is written into the fixed data track of the forged card which is separately prepared for forging the card, the detection coil 161 of the head MD 1' is disconnected and the forged card cannot be generated by using the card processor.
