See full text

Aspects of the disclosure provide a method for detecting land pre-pits. The method includes detecting, based on a land pre-pit threshold, a land pre-pit data stream from a signal responsive to land pre-pits on an optical medium, comparing a characteristic of the detected land pre-pit data stream in a specific number of wobble periods with a pre-determined land pre-pit characteristic in the specific number of wobble periods, and adjusting the land pre-pit threshold based on the comparison.
