Abstract:
According to one embodiment, a magnetic recording head includes a disk-facing surface configured to face a recording layer of a recording medium, a main magnetic pole includes a distal end located on the disk-facing surface and configured to apply a recording magnetic field to the recording layer of the recording medium, a leading shield on a leading side of the main magnetic pole, opposed to the distal end of the main magnetic pole across a gap, a high-frequency oscillator between the leading shield and the distal end of the main magnetic pole, and a recording coil configured to excite the main magnetic pole with a magnetic field.
