The circuit for separating the video disk data comprises an input unit (10) which applies the complexed video signal inserted with a disk information to a clamp circuit (20), a first low pass filter (30) for reducing the high frequency components of color signal and brightness signal in the complexed video signal, an amplification section (40) for amplifying the signal of the first low pass filter, a first level shifter, a second level shifter, an integrator (70) for converting the input video signal to DC component, a third level shifter (80), and comparators (30),(110),(140).
