ABSTRACT:
A signal level adjusting unit adjusts levels of EFM signals, read from an optical disk, to given levels, and comprises a peak value detector, a peak value comparing circuit issuing a control signal on the basis of the difference between a peak value and a reference value, a bottom value detector, a bottom value comparing circuit issuing a shift signal in accordance with a difference between a bottom value and a reference value, an amplifier amplifying the EFM signal with an amplification factor in response to the control signal, and a level shift circuit level-shifting the EFM signals in response to the level shift signals.
