Abstract
A method and apparatus for integrating a stair notch and a gap bump at a pole tip in a write head is disclosed. A protective plated layer is formed over the bump to prevent the bump form being damaged during formation of the notch at the pole tip. The flux from the second pole outside of the track will be effectively channeled to the first pole piece under the alumina bump.
