摘要：
A magnetic write head having a main magnetic write pole and a magnetic sub-pole that are configured to maximize magnetic performance. The main magnetic write pole has a flared portion located near the air bearing surface and a non-flared portion removed from the air bearing surface. A magnetic sub-pole is formed adjacent to the main magnetic write pole and terminates at a front endpoint that is recessed from the air bearing surface but is closer to the air bearing surface than the non-flared portion.
