摘要：
An apparatus may be constructed with a magnetic element, such as a data transducing head. A first permanent magnet may be configured to bias the write pole to decrease remnant magnetization and erasure after write (EAW). The first permanent magnet can be separated from the write pole be a predetermined distance.
