ABSTRACT:
A disc recording/playback apparatus adapted to obtain data of recorded signals at the maximum level within a predetermined period in the signal recorded on an erasable medium per each predetermined period from a signal recording start point to end point and to record them as waveform data of the recorded signal in a different recording area from that of the recorded signal. A compressed envelope waveform of the recorded signal may be displayed on a display section by supplying the waveform data continuously to the display section, so that broad signal changes can be understood by viewing them.
