Abstract
A magnetic head includes a coil, a main pole, and a return path section. The return path section includes a coil surrounding portion located on the front side in the direction of travel of a recording medium relative to the main pole and provided for forming a coil receiving space, and a connecting portion connecting the main pole and the coil surrounding portion to each other. The connecting portion has a contact surface in contact with the main pole. The coil receiving space is a space defined by a first virtual plane intersecting the contact surface and parallel to a medium facing surface, a second virtual plane including the contact surface and perpendicular to the direction of travel of the recording medium, and the coil surrounding portion. The coil includes a portion received in the coil receiving space.
