Therefore, a recorded dot length in a depth direction is monitored 111 and a power of the laser light is adjusted based on the monitored recorded dot length, or a difference between a focus position where a region of the recorded dots appears brighter than the surroundings and a focus position where the region of the recorded dots appears darker than the surroundings is measured and the power of the laser light is adjusted based on the difference."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical recording device, optical recording method, and optical recording medium","description":"When recording is performed by focusing a short pulse laser on an inside of a transparent medium such as quartz glass, and forming a minute deformed region in which the refractive index is different f","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9653108","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.
