| 英文摘要 | A thermally assisted magnetic recording head includes core that propagates laser light as propagation light, a near-field light generator that faces a portion of the core and extends to an air bearing surface (ABS), the near-field light generator coupled to the propagation light propagating through the core so as to generate a surface plasmon, propagating the surface plasmon to an end part facing the ABS, and generating near-field light at the end part to irradiate the near-field light to a magnetic recording medium, a main magnetic pole layer provided in the vicinity of the near-field light generator where an end part is positioned on the ABS, a laser diode that generates laser light of wavelength 890 nm to 1,000 nm and enters the laser light into the core, and a photodiode provided on a silicon substrate measures an intensity of the laser light entering from the laser diode to the core. |
