ABSTRACT:
The invention provides a thin film magnetic head including an upper core layer 9 which comprises a front first core layer 91a formed on a gap spacer layer 6 and having the same width as a track width on the recording medium at least in the vicinity of the face to be opposed to a recording medium, and a second core layer 92 extending from the medium-opposed face over the upper surface of the front first core layer 91a and further over the upper surface of an upper insulating layer 72. The upper core layer 9 has a thickness greater in a region extending from the medium-opposed face to a depth end restricting face DE of a lower insulating layer 71 than in a region extending over the upper surface of the upper insulating layer 72. The front first core layer 91a has an upper surface flush with the upper surface of the lower insulating layer 71. This structure gives an accurate track width and assures production with a high yield.
