摘要： This magnetic recording device is provided with a magnetic write head having a magnetic pole, and a magnetic recording medium having a plurality of data recording blocks. Each of the data recording blocks is formed with a plurality of write tracks, and separated, in a write track width direction, from neighboring one of the data recording blocks with a writing exudation suppression section in between. With this configuration, a magnetic mutual interference of the adjacent data recording blocks at the time of a data rewriting process is avoided even when a mutual interval of the data recording blocks is narrowed, and a good recording state is maintained in each of the data recording blocks. Therefore, it is possible to achieve an improvement in a recording density, while realizing the good and brief data rewriting process for each of the data recording blocks.

摘要： A thermally-assisted magnetic recording head includes a main pole, a waveguide, and a plasmon generator. The main pole has a front end face including first and second ends that are opposite in a track width direction. An arbitrary cross section of the main pole that passes through an arbitrary point on the front end face and is perpendicular to a medium facing surface and to the track width direction has a length in a direction perpendicular to the medium facing surface. When the arbitrary point on the front end face is located at a center of the front end face in the track width direction, the length of the arbitrary cross section is smaller than that when the arbitrary point is located at the first end and that when the arbitrary point is located at the second end.
