A reproducing apparatus for reproducing manufacturer information for supporting specific functions and a method therefor is also provided. If a recording apparatus modifies the contents of the recording medium, then it should record its manufacturer's identification code. A recording apparatus/reproducing apparatus should check the identification code on the recording medium before using its own manufacture information item for some specific function. Also, it is possible to reduce the time required to determine whether the manufacturer information items are effective."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for recording manufacturer information on a recording medium and for determining whether the manufacturer information is effective","description":"A recording medium and a recording apparatus for storing manufacturer information for supporting specific functions for each manufacturer and a method therefor.
