The method include: opening a tray on which a disc in which a first magnet is installed is loadable; moving a feeding unit to a position where attraction between a second magnet installed in the feeding unit and the first magnet is relatively low; and if the tray is closed, placing a center of the disc in a turn table."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Disc chucking method and disc driving apparatus","description":"Provided are a disc chucking method of preventing mis-chucking from occurring according to a state and direction of a disc loaded onto a tray when the tray is closed, and a disc driving apparatus for ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8490122","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.
