1. A magnetic head for detecting a magnetic field on the surface of a magnetic pattern based on magneto-resistance technology, comprising:

  • a frame;

    a printed circuit board (PCB) arranged on the frame;

    permanent magnets structure for generating a magnetic field parallel with the surface of the magnetic head; and

    a magnetic sensor based on magneto-resistive (MR) elements, which is used for detecting the distribution of the vertical component of a magnetic field on the surface of the magnetic pattern.
