Summary:A heat-assisted magnetic recording head mounted on an end of a slider having an Air Bearing Surface ('ABS') for recording data on a recording medium. The heat-assisted magnetic recording head includes a magnetic path forming unit that generates a magnetic field for recording the data, a light source that emits light heating a local region of the recording medium, a waveguide located on a side of the magnet path forming unit to transmit the light emitted from the light source, an optical path conversion unit that changes a direction of the light transmitted from the waveguide to the local region of the recording medium, and a nano-aperture that generates an enhanced near-field effect by converting an energy distribution of the light transmitted via the optical path conversion unit.
