The light source unit can reduce mechanical stress and thermal conduction between a light source assembly and a substrate member, thereby improving the performance of the light source assembly and the heater."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light source unit and thermally-assisted magnetic head","description":"A light source unit for thermally-assisted magnetic head includes a substrate member having a first bonding surface; a light source assembly attached on the first bonding surface of the substrate memb","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11973310","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.
