Abstract
According to one embodiment, a magnetic recording head in a magnetic disk drive with a recording medium includes a magnetic core including a plurality of magnetic poles which form a closed magnetic path, and a recording coil wound around a part of the magnetic core and produces a magnetic field to the magnetic core. The magnetic core includes a write gap formed of a nonmagnetic material in a disk-facing surface of the recording head, a magnetic gap portion located at a position off from the disk-facing surface and magnetically isolated, and a nonmagnetic material in the at least one magnetic gap portion. The recording coil is wound around the nonmagnetic material in the magnetic gap portion.
