Abstract:
A method and system for manufacturing a pole for a magnetic recording head. The method and system include providing an insulator and fabricating at least one hard mask on the insulator. The at least one hard mask has an aperture therein. The method and system also include removing a portion of the insulator to form a trench within the insulator. The trench is formed under the aperture. The method and system further include depositing at least one ferromagnetic material. The pole includes a portion of the ferromagnetic material within the trench.
