ABSTRACT:
When a video signal is recorded on a magnetic tape (14), a high frequency signal component of data converted by a DCT (discrete cosine transform) converter (3) in a DCT fashion or an outer code is recorded on a recording track at its beginning portion in which a waveform of a reproduced output is considerably deteriorated in amplitude when a reproducing head (15) starts to reproduce the recording track. Also, a low frequency signal component of data converted by the DCT converter (3) in a DCT fashion is recorded on the recording track at its succeeding portion in which the reproducing head (15) can stably reproduce the recording track by a recording head (13). The high frequency signal component or outer code is recorded on the area corresponding to the track at its beginning portion in which a waveform of a reproduced output is considerably deteriorated in amplitude when the reproducing head starts to reproduce the same upon playback and the low frequency signal component of data is recorded on the track at its succeeding portion in which the tracing of the reproducing head is stabilized relatively so that, even if a reproducing error occurs and increases because a waveform of a reproduced output is deteriorated in amplitude when the reproducing head starts to trace the recording track, then an amount that a picture quality of a reproduced signal is deteriorated by such error can be reduced considerably.
