Abstract
Approaches for a magnetic write head having a hybrid material main pole, in which a first magnetic material has a first cross-sectional area (A1) and a second magnetic material has a second cross-sectional area (A2), and wherein the ratio A1/A2 reduces in a direction away from the air bearing surface. The first material comprises a high saturation magnetic flux density material, and the second material comprises a high magnetic permeability and low saturation magnetic flux density material having a lower saturation magnetic flux density than said first material.
