The write head unit includes a main pole, a write shield, and a return path section. The return path section includes a yoke layer located backward of the main pole along the direction of travel of the recording medium, a first coupling part that couples the yoke layer and the write shield to each other, and a second coupling part that is located away from the medium facing surface and couples the yoke layer and the main pole to each other."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Magnetic head for perpendicular magnetic recording that includes a sensor for detecting contact with a recording medium","description":"A magnetic head for perpendicular magnetic recording includes a read head unit, a write head unit disposed forward of the read head unit along the direction of travel of a recording medium, a heater t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9773514","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.
