ABSTRACT:
In an apparatus for magnetic digital data recording and playback, a waveform equalizer circuit thins a signal reproduced from a magnetic recording medium in order to correct a waveform of the signal. Both the gain and phase are designed variable during recording and reproduction of the digital signal, so that the reproduced signal can be equalized under any desired frequency and phase characteristics without intercode interference among solitary waveforms which appear upon magnetic flux reversals.
