摘要:
According to one embodiment, a recording head includes a main pole, a trailing core, a first coil wound around the trailing core, a leading core, and a second coil wound around the leading core. The trailing core includes a return pole opposed to a trailing side of the main pole with a write gap therebetween, and side shields arranged individually on opposite sides of the main pole transversely relative to tracks and magnetically separated from the main pole at a distance not more than double a track pitch of the recording medium. The leading core includes a junction opposed to a leading side of the main pole with a gap therebetween and joined to the side shields with a width of 20 μm or less transversely relative to the tracks and a connecting portion joined to the main pole in a position off the recording medium.
