PURPOSE:To omit the bias electrode, to simplify the structure and to facilitate the manufacture by adopting the structure that the magnetic anisotropy is given while being tilted by a prescribed angle in the lengthwise direction of the yoke section. CONSTITUTION:After an insulation layer 7 is formed on a magnetic base 6, the signal electrode 2 is formed on the layer 7 to obtain a prescribed pattern. Then the MR film is formed on the layer 7 to form a prescribed shape of the MR element 1. Then the insulation layer 9 is formed on the upper side of the element 1, further the layers 7, 9 are subject to ion etching to form a front magnetic gap 11 and a back throughhole 12. Succeedingly, a front yoke 4 and a tail yoke 5 are formed, the magnetic anisotropy tilted by 45 deg. in the lengthwise direction of the yokes 4, 5 is given to form a prescribed pattern, and the yokes are overlapped slightly onto the element 1. Further, the insulation protecting film 10 is coated over the entire face to complete the MR head. |
