Patent ID: 8705204

Claim:
A recording head comprising: a main pole configured to produce a recording magnetic field perpendicular to a recording layer of a recording medium; a trailing shield on a trailing side of the main pole with a write gap therebetween; a recording coil configured to produce a magnetic field in the main pole; and a high-frequency oscillator between the trailing shield and a tip portion of the main pole, wherein the main pole comprises a first magnetic pole layer located on a leading side and a second magnetic pole layer laminated on the trailing side of the first magnetic pole layer, the first magnetic pole layer comprises a first tapered portion tapered toward the recording medium and a first tip portion having a predetermined width and extending from the first tapered portion toward the recording medium, the second magnetic pole layer comprises a second tapered portion tapered toward the recording medium and a second tip portion having a predetermined width and extending from the second tapered portion toward the recording medium, a width in a track direction of the second tip portion is smaller than that of the first tip portion, the high-frequency oscillator being between the second tip portion and the trailing shield and comprising 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 being taller than that of the second tip portion.
