ABSTRACT:
The present invention provides a method for automatically tuning a pre-pit slicing level and a related apparatus. The pre-pit slicing level can be used for slicing a first signal generated by an optical storage device when reading an optical storage disc to identify at least one pre-pit signal within the first signal. The method includes finding a first maximum according to the first signal, and generating the pre-pit slicing level according to the first maximum so that the optical storage device is capable of identifying the pre-pit signal within the first signal.
