The head body includes a main pole, a waveguide, a plasmon generator, and a main light-blocking section. The waveguide has an entrance end face and an exit end face. The plasmon generator has a near-field light generating surface. The medium facing surface includes a first region including neither of the exit end face and the near-field light generating surface, and a second region including the exit end face and the near-field light generating surface. The protective film includes a first portion covering the first region, and a second portion covering the second region. The main light-blocking section is located to intersect an imaginary straight line connecting the entrance end face and the first region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Thermally-assisted magnetic recording head and manufacturing method therefor","description":"A head includes a head body having a medium facing surface, and a protective film covering the medium facing surface.
