Abstract:
A method for forming either of two magnetic pole layers of a thin film magnetic head comprising first and second magnetic pole layers which are magnetically coupled to each other, which include magnetic pole portions being opposite to each other and being placed in regions of the magnetic pole layers on the side of surfaces thereof facing a recording medium and which are each constituted by at least one layer, a gap layer provided between the magnetic pole portion of said first magnetic pole layer and the magnetic pole portion of said second magnetic pole layer and a thin film coil provided such that at least a part thereof is interposed between said first and second magnetic pole layers in a state of insulation from said first and second magnetic pole layers, said method including the steps of:forming an electrode film used for forming said magnetic pole layer; forming a reflection preventing film which is conductive and which has a function of preventing reflection of light for exposure at photolithography on said electrode film; forming a photoresist pattern for forming said magnetic pole layer on said reflection preventing film using photolithography; and forming said magnetic pole layer using said photoresist pattern as a mask.
