The present invention relates to a magnetic head manufacturing method used for a magnetic storage device. The method includes the steps of forming a first groove in a shape corresponding to an outline of a main magnetic pole on an insulation layer; forming a second groove corresponding to an outline of a main magnetic pole brace layers; inside the outline of the main magnetic pole; and using a plating method to fill the first and second grooves at the same time with a ferromagnetic material and form a main magnetic pole and a main magnetic pole brace layer at the same time.
