Method for fabricating a thin film magnetic head

摘要

A writing magnetic pole portion composed of a first magnetic film and a second magnetic film formed on the first magnetic film via a gap film is fabricated on a given wafer. Then, the writing magnetic pole portion is swung forward and backward around a rotation standard axis parallel to a center line of the writing magnetic pole portion in a direction parallel to a surface of the. Then, the writing magnetic pole portion is milled during the swing of the writing magnetic pole portion to define the width of the writing magnetic pole portion.
