A perpendicular magnetic recording (PMR) head is provided which records data in a PMR medium. The PMR head includes a main pole having an end portion disposed on an air bearing surface (ABS) opposed to the PMR medium and the other end portion; a return yoke spaced apart from the main pole; a sub-yoke starting from the other end portion of the main pole and extending away from the PMR medium, so as to magnetically connect the main pole with the return yoke; and a coil disposed to encircle the sub-yoke. |
