Abstract:
According to one embodiment, a magnetic recording head includes a disk-facing surface, a main pole, a trailing shield, a first junction which connects the trailing shield and the main pole in a position off the disk-facing surface, a second junction which includes a high-frequency oscillator and connects the trailing shield and the main pole on side of the disk-facing surface, a leading shield on the leading side of the main pole, including a junction connected to the main pole in a position off the disk-facing surface with a third junction therebetween, and a connecting terminal configured to pass a current in series through the main pole, the nonmagnetic conductive layer, and the trailing shield. A thickness of the third junction is smaller than that of the first junction.
