ABSTRACT:
A main magnetic pole of a magnetic head for perpendicular magnetization is made in a sputtering apparatus by continuously moving a shielding plate closely to a substrate in a space between the substrate and a target electrode standing face to face with each other, whereby the thickness of a soft-magnetic metal film formed on the substrate by sputtering is continuously changed.
