摘要： The present invention provides a magnetic writer. The magnetic writer comprises a write circuit, a write pole, a first write coil for inducing a first magnetic field in the write pole by a first current provided by the write circuit, and a second write coil for inducing a second magnetic field in the write pole by a second current provided by the write circuit. The write circuit provides a first current through the first coil and a second current through the second coil. The write circuit controls the direction of the first current and the second current so that, during writing, the first magnetic field and the second magnetic field have components perpendicular to the air bearing surface that are in the same direction. When not writing, the first magnetic field and second magnetic field have components perpendicular to the air bearing surface in opposite directions.
