| 英文摘要 | In a heat-assisted magnetic recording head, as a result of such disturbances as temperature change or vibration or degradation of a semiconductor laser due to time, intensity of light transmitted through a waveguide fluctuates. If the intensity of the light that is incident to a surface of a medium fluctuates, a magnetic recording device becomes unable to perform recording in a stable manner. In order to resolve such issues, a near-field light-generating element (32) is placed in a vicinity of an air bearing surface (ABS) of a slider (30), and a magnetic recording and reproducing element (34) is provided adjacent to the near-field light-generating element (32). On an opposite surface of the ABS of the slider (30), a laser diode unit (31) is equipped, and light emitted from the laser diode unit (31) passes through the waveguide (33) and irradiates the near-field light-generating element (32). The near-field light-generating element (32) is connected to electrode pads (40, 41) through conductor lines (42, 43). The near-field light-generating element (32) also functions as a temperature-sensing element. |
