摘要： PROBLEM TO BE SOLVED: To provide a thin-film magnetic head for heat-assisted magnetic recording, which forms stable recording bit pattern having steep magnetization transition regions without using a near-field light generating element.
SOLUTION: This head is provided with: a waveguide for guiding light to a magnetic recording medium, and a write head element formed at a trailing side of the waveguide and having a write magnetic pole. Here, a write magnetic field profile which is related to a position of a direction along a track in the recording layer of the magnetic recording medium and which shows an intensity distribution of the write magnetic field generated from the write magnetic pole has a projecting region on a leading side. Further, an anisotropy magnetic field profile which shows a distribution of the anisotropy magnetic field for a position of a direction along the track when the anisotropy magnetic field of a part of the recording layer is reduced by irradiation of the light from the waveguide traverses this projecting region of the write magnetic field profile. Thereby, the formed recording bit of the magnetization transition region becomes steep.
