PURPOSE:To facilitate easy formation of a desired anisotropic magnetic domain structure by forming a pattern different from the form of a magnetic head core at the outside of a photoresist pattern that prescribes the core width and therefore eliminating an anisotropic magnetic field of the core form which is decided by the form of the core. CONSTITUTION:A core pattern 12 corresponding to the contour form of a magnetic head core is formed in a frame shape on a plating conductor layer 11 by patterning of photoresist. At the same time, an anisotropy application pattern 13 which is long laterally is formed in a frame shape at the left and right sides of the core tip part (corresponding to a part 12a of the pattern 12) to which the lateral anisotropy is not easily given by patterning of photoresist. Then a magnetic film 14 of ''Permalloy'', etc. is formed by electroplating on the layer 11 containing patterns 12 and 13. In other words, a form anisotropic magnetic field at a magnetic film part 14b corresponding to a core tip part is eliminated by the form anisotropic magnetic field of a magnetic film part 14a and an externally impressed magnetic field shown by an arrow A. |
