摘要：
A magnetic recording head includes a write pole and a first permanent magnet. The write pole has a write pole tip, a leading edge, a trailing edge, a first side and a second side. The first permanent magnet is located either at the trailing edge of the write pole, the first side of the write pole or at the second side of the write pole. The first permanent magnet has a magnetization orientation that is changed in relation to a field of the write pole.
