Abstract
A signal corresponding to data read from an optical storage medium is equalized to generate an equalized signal. A signal level of the equalized signal is determined, and an expected signal level of the equalized signal without high frequency distortion is determined. A comparison between the signal level of the equalized signal and the expected signal level is performed, and an amplitude of the equalized signal is adjusted based on the comparison of the actual signal level of the equalized signal and the expected signal level. The equalized signal is decoded after adjusting the amplitude of the equalized signal.
