Abstract:
A method of forming a magnetic layer pattern on a surface of a predetermined underlayer, including:a first step of forming a frame pattern having an opening with a predetermined shape on the underlayer; a second step of forming at least a precursory magnetic layer as a preparatory layer for the magnetic layer pattern so as to cover at least a region including the opening of the frame pattern; and a third step of forming the magnetic layer pattern by polishing at least the precursory magnetic layer until at least the frame pattern is exposed, wherein the second step includes the steps of: forming at least a pair of precursory magnetic layers; and forming a precursory nonmagnetic layer between each precursory magnetic layer, and the third step includes polishing the at least a pair of precursory magnetic layers and the precursory nonmagnetic layer.
