ABSTRACT:
The method of manufacturing a thin-film magnetic head in accordance with the present invention comprises the steps of forming a first magnetic pole layer; removing both sides in a track width direction of the first magnetic pole layer so as to leave a predetermined residual area in the first magnetic pole layer; forming an insulating layer about the residual area of the first magnetic pole layer; forming a gap layer made of a nonmagnetic material; forming a second magnetic pole layer magnetically connected to the first magnetic pole; and patterning the second magnetic pole layer by etching while using a mask.
