Abstract
A digital VTR is provided for recording data for one-frame of video and audio signals, which have been error-correcting-encoded collectively, in a predetermined number of pieces of tracks during normal recording and for recording data for the video and audio signals, which have been error-correcting-encoded collectively, in one less than the predetermined number of tracks and data for the audio signal, which have been error-correcting-encoded during post-scoring, in the remaining one track exclusively for the post-scoring during post-scoring audio recording.
