A wave reforming circuit for correcting the upward and downward asymmetry of and binary coding a data train signal modulated by EFM modulation or another modulation method giving a substantially equal rate of occurrence of "1" and "0", which can output to a comparator outputting binary data a binary signal holding a predetermined temporal mean value regardless of fluctuation in the temporal mean value of the input signal and having superior symmetry compared with the related art using as a reference value three types of reference voltages (0 level, positive side, and negative side) generated by inputting an integrated value of the output of the comparator into a charge pump.
