Abstract:
1. A method for manufacturing a thin-film magnetic head having a soft magnetic film, including a lower core layer, an upper core layer, and a magnetic pole portion which is provided between the lower core layer and the upper core layer and which has the width in the track width direction formed smaller than that of each of the lower core layer and the upper core layer, the method comprising: forming a lower magnetic pole layer in contact with the lower core layer, an upper magnetic pole layer in contact with the upper core layer, and a gap layer provided between the lower magnetic pole layer and the upper magnetic pole layer so as to form the magnetic pole portion; or, forming an upper magnetic pole layer in contact with the upper core layer, and a gap layer provided between the upper magnetic pole layer and the lower core layer so as to form the magnetic pole portion, wherein at least one of the upper magnetic pole layer and the lower magnetic pole layer is formed of a soft magnetic film by a method of plating, the method comprising: forming a Co
