According to one embodiment, a magnetic head includes a magnetic core including a main pole, and a return pole opposed to the main pole with a magnetic gap therebetween, and configured to return magnetic flux from the main pole and form a magnetic circuit in conjunction with the main pole, a coil configured to excite magnetic flux in the magnetic circuit, and a nonmagnetic electrically conductive layer formed by disposing only a nonmagnetic material in the magnetic gap between the return pole and an end portion of the main pole on the recording medium side, and configured to electrically connect the main pole and the return pole. The main pole, the nonmagnetic electrically conductive layer, and the return pole are configured to constitute a series electrical circuit.
