Abstract
According to an embodiment, a magnetic head for perpendicular recording, includes a slider including a facing surface opposed to a recording medium, and a head portion on the slider and configured to perform information processing for the recording medium. The head portion includes a main pole configured to apply a perpendicular recording magnetic field to the recording medium, a recording coil configured to excite the main pole, a write shield pole opposing the main pole across a write gap, side shields arranged individually on opposite sides of the main pole in a track width direction and magnetically isolated from the main pole, and low-flux-density layers formed of a material having a saturation magnetic flux density lower than that of the main pole, located between the main pole and the side shields, and configured to regulate magnetic fluxes flowing from the main pole to the side shields.
