ABSTRACT:
A recording method is provided for a video tape recording apparatus having modes for recording PCM audio signals in a plurality of transmission rates. Index codes for a video signal, which enable a search reproduction and so on, are recorded on a video tape in a constant transmission rate irrespective of the transmission rate of a PCM audio signal to be recorded. Further, an amble pattern at the same frequency as the transmission rate of the PCM audio signal is recorded immediately behind the PCM signal recording area. A reproducing apparatus may be provided only with an index detecting circuit corresponding to the constant transmission rate.
