    摘要: According to one embodiment, a main pole of a recording head includes a first magnetic pole layer and a second magnetic pole layer laminated on the trailing side of the first magnetic pole layer. The first magnetic pole layer includes a tapered portion and a first tip portion. The second magnetic pole layer includes a tapered portion and a second tip portion. A width in a track direction of the second tip portion is smaller than that of the first tip portion. The high-frequency oscillator is between the second tip portion and the trailing shield and includes a width in the track direction substantially equal to the width in the track direction of the second tip portion, and a height of the first tip portion is taller than that of the second tip portion.

    摘要: According to one embodiment, a method of manufacturing a magnetic recording head includes forming a main pole, forming an oscillator forming layer includes an underlayer, a spin injection layer, an interlayer, an oscillator layer, and a cap layer on a trailing end surface and sidewalls of the main pole, and removing those parts of the oscillator forming layer which are formed on the sidewalls of the main pole, thereby forming a high-frequency oscillator which is aligned with a width of at least the trailing end surface of the main pole.
