The method incorporates forming a magnetic core within the plasmon antenna, so the antenna effectively becomes an extension of the magnetic pole and produces a magnetic field whose maximum gradient overlaps the region being heated by the edge plasmons generated in the conducting layer of the antenna surrounding the antenna's magnetic core."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of forming a plasmon antenna with magnetic core for thermally assisted magnetic recording","description":"A method of forming a TAMR (Thermal Assisted Magnetic Recording) write head that uses the energy of optical-laser generated edge plasmons in a plasmon antenna to locally heat a magnetic recording medi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8503271","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.
