The method includes extracting a land pre-pit data stream from a signal responsive to land pre-pits on an optical medium based on a land pre-pit threshold, detecting a bit stream pattern from the land pre-pit data stream, comparing one or more bits in the land pre-pit data stream at locations relative to the bit stream pattern with pre-known bit information, and adjusting the land pre-pit threshold based on the comparison."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for detecting land pre-pits","description":"Aspects of the disclosure provide a method for detecting land pre-pits.
