    Abstract: A card reader (1) is provided with: a pre-head (50) which detects change in the magnetic field by magnetoresistive elements (21, 22); a voltage applying circuit (23) which applies a voltage to the pre-head (50); and a reference voltage circuit (30) which superimposes a reference voltage (V0) onto the voltage signal (S1) from the pre-head (50); the card reader is also provided with a signal processing circuit (24) which outputs a detection signal (S4) on the basis of the difference between the voltage signal (S1) and the reference voltage V0. Further, the card reader (1) is provided with a coupling capacitor (26) which is inserted between the pre-head (50) and the signal processing circuit (24), and a switching circuit (27) which connects the coupling capacitor (26) and the signal processing circuit (24) at the same time that voltage is applied to the pre-head (50) from the voltage applying circuit (23).

    Abstract: A demodulation method of magnetic data may include a first data creating step which creates a preliminary data string for creating the demodulation data on a basis of an interval that is a time interval between peaks of a read signal of an analog-shaped magnetic data, and a second data creating step which creates a demodulation data creating data for creating the demodulation data on a basis of the preliminary data string created in the first data creating step. When a peak of the read signal is not detected for a predetermined time, a pseudo-peak is generated and a pseudo-interval is stored in a data storage section, and steps similar to the first data creating step and the second data creating step are executed, and the pseudo-peak is generated until the demodulation data creating data corresponding to a final interval is created.

    Abstract: This magnetic head, which reads and writes magnetic information, prevents a signal from being read between the magnetic head and the write circuit during reading of magnetic information. A card reader 1 is provided with a magnetic head 6 which reads and writes magnetic information. Bidirectional diodes 54A, 54B are arranged inside of a head case 21 of the magnetic head 6. A write signal from a write circuit 72 is inputted via the bidirectional diodes 54A, 54B to a writing coil 34 wound around a core 32 of the magnetic head 6. The bidirectional diodes 54A, 54B and a demodulation IC 61 are mounted on a first board surface 62A of a control circuit board 62, and the control circuit board 62 is fixed to the head case 21 so that the bidirectional diodes 54A, 54B and the demodulation IC 61 are covered by the head case 21.
