In one illustrative example, a method for use in making a magnetic write head includes the steps of forming a first pole piece layer of a first pole piece; forming a patterned resist over the first pole piece layer; electroplating a pedestal over the first pole piece layer within a channel of the patterned resist; electroplating a metal gap layer over the pedestal within the channel of the patterned resist; forming a resist channel shrinking film over the patterned resist; baking the resist channel shrinking film over the patterned to thereby reduce a width of the channel; removing the resist channel shrinking film; electroplating a second pole piece within the reduced-width channel of the patterned resist; removing the patterned resist; and milling the pedestal, using the second pole piece as a mask, to form a central notched pedestal having side walls with angled slopes.
