摘要：
A method for forming a magnetic write head having a trailing shield with a tapered and stepped, self aligned trailing magnetic shield. The shield has a tapered portion that tapers away from the write pole as it extends away from the ABS. This tapered portion helps to channel flux to the pole tip portion of the shield, while preventing the loss of write field to the shield. The stepped portion of the shield further helps to prevent the loss of write field and also defines a secondary throat height of the shield that can be accurately located relative to the air bearing surface.
