Optimum slice level signal reading apparatus for optical disk

摘要

An apparatus for reading information from an optical disk, comprises a rotator to rotate the optical disk, a detector to detect optical information from the optical disk and to output signals, AC coupling section to eliminate signal components lower than a predetermined cut-off frequency from the signals, a slice level signal generator to generate slice level signals from a peak value and a bottom value of the signals; and a data outputting section to obtain data outputs from the signals and the slice level signals.
