MAGNETIC RECORDING HEAD AND DISK DRIVE WITH THE SAME |
| 摘要 |
According to one embodiment, a magnetic recording head includes a medium-facing surface, a near-field transducer partially exposed in the medium-facing surface, and a magnetic pole including a distal end surface and a pole end surface facing the near-field transducer. The pole end surface in the medium-facing surface is asymmetric with respect to a central axis passing through a center of the near-field transducer and extending in a longitudinal direction of the medium-facing surface. |

1. A magnetic recording head comprising:
a medium-facing surface configured to face a recording layer of a disk recording medium; a near-field transducer partially exposed in the medium-facing surface and configured to emit a near-field light which heats the recording medium; and a magnetic pole comprising a distal end surface exposed in the medium-facing surface and a pole end surface facing the near-field transducer and configured to apply a recording magnetic field to the recording layer of the recording medium, the pole end surface in the medium-facing surface being asymmetric with respect to a central axis passing through a center of the near-field transducer and extending in a longitudinal direction of the medium-facing surface. |
