Abstract

PURPOSE:To obtain the said head having accurate gap, by two sections at the boundary of the gap and forming the second upper magnetic layer via the insulation layer so that it is overlapped with the taper being the gap of the first upper magnetic substance layer, in forming the upper magnetic layer of thin film magnetic head. CONSTITUTION:In manufacture of thin film magnetic substance head, the lower magnetic substance layer 7 is formed on the substrate 6, the coductor coil 9 is formed via the insulation layer 8 on it, and the fist magnetic substance layer 11 is formed on it via the insulation layer 10. Next, the resist 12 is formed so that the end comes to the part forming the gap and the taper is provided on the first upper magnetic substance layer with etching. Next, on it, the magnetic insulation layer 13 and the magnetic substance layer 14 are formed, and after forming the resist 16 on the part being the second upper magnetic substance layer of the magnetic substance layer 14, the magnetic substance layer on the first upper magnetic substance layer 11 is removed with etching, the upper surface of the first upper magnetic substance layer 11 and the second upper magnetic substance layer 15 is finished smooth on the same plane to constitute the gap 17.
