Abstract
A magnetic head includes first and second coils, a main pole, a write shield, a return path section, and a yoke. The return path section is located on the front side in the direction of travel of a recording medium relative to the main pole. The yoke is located on the rear side in the direction of travel of the recording medium relative to the main pole. The first coil is wound around the main pole. The second coil is located on the rear side in the direction of travel of the recording medium relative to the main pole so as to pass between the main pole and the yoke.
