Abstract
An apparatus for improving decoding accuracy of an equalized signal having a direct current (DC) level obtained from an optical disk is provided. A Viterbi decoder is configured to decode the equalized signal and output a Viterbi-decoded signal. A DC controller is configured to adjust the DC level of the equalized signal such that the equalized signal with the adjusted DC level is decoded.
