Abstract
An optical signal conversion apparatus in a compact disk player detects peaking in an RF signal read from a disk and compensates to reproduce a stable conversion signal, for example an EFM signal. In the optical signal conversion apparatus, a peaking prevention portion detects peaking of the RF input signal and outputs a predetermined reference voltage, if the peaking is detected, or alternately the input signal, if the peaking is not detected. A waveform processing portion extracts a high frequency component from the signal output from the peaking prevention portion, slices the extracted signal as a predetermined level, and outputs the sliced signal.
