PURPOSE:To eliminate the element width loss of a thin film magnetic head, by setting an end of the width direction of a magneto-resistance effect element of a ferromagnetic matter opposite to a recording medium, connecting magnetically the other end of the magneto-resistance effect element to a magnetic matter and then setting an end of the magnetic matter opposite to the recording medium. CONSTITUTION:A cut groove 2 is formed on the surface of an insulated magnetic substrate 1 of ferrite, etc., and a nonmagnetic material 3 is filled into the groove 2. Then an Ni-Fe alloy, for instance, is coated over a new surface finished with the same level as the surface of the substrate 1. Electrodes 5 and 6 are provided at both ends of the lengthwise direction of a magneto-resistance effect element 4, and the element 4 is set in parallel to the lengthwise direction of the groove 2. The upper end part of the element 4 is connected magnetically to the upper end part 9 of the groove 2, and the lower end part of the element 4 touches a recording medium 7. The surface 10 which is approximately rectangular to the element 4 touches the medium 7. The signal magnetization recorded to the medium 7 is led from the lower end part of the element 4 and then to the part 9 through the element 4. Then the signal magnetization is led to the surface 10 through the substrate 1 and returns to the medium 7. As a result, both the element width loss and the gap loss can be eliminated. |
