An optical waveguide introduces a light beam from the light source into the head to generate near-field light. A control section supplies a current to a recording element of the head for generating a recording magnetic field in a direction of the medium. A photoelectric composite wiring line has the optical waveguide and electric wiring lines integral with the optical waveguide. The optical waveguide is arranged between the electric wiring lines. The optical waveguide and the electric wiring line branch off from a distal side of the photoelectric composite wiring line so that the optical waveguide is routed to a base end surface of the near-field light head in a state extending approximately linearly."},"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 having photoelectric wiring lines integrally formed on waveguide","description":"An information recording and reproduction apparatus has a magnetic recording medium, a light source that outputs a light beam to heat the medium, and a near-field light head confronting a surface of t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8537646","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
