Abstract:
1. A method for manufacturing a thin-film magnetic head, comprising: (a) a step for forming an under layer on a substrate; (b) a step for forming in said under layer a first recess which extends in a height direction from a face facing a recording medium, and a second recess which extends in the height direction, in the under layer distanced from said first recess by a predetermined distance; (c) a step for forming a lower shield layer by embedding in said first recess, and forming a first metal layer by embedding in said second recess; (d) a step for forming an upper face of said lower shield layer, an upper face of said first metal layer, and an upper face of said under layer, as coplanar; and (e) a step for forming a magnetoresistance effect element on said lower shield layer and forming an upper shield layer on said magnetoresistance effect element.
