ABSTRACT:
A PCM recording and reproducing apparatus record digital signals obtained by sampling and quantizing analog signals on a recording medium after adding control words, synchronizing signals, etc. to the digital signals. The PCM recording and reproducing apparatus includes means for setting sampling frequencies, means for controlling the speed of recording the signals on said recording medium so as to comply with the set sampling frequency, means for generating sampling frequency indicating codes, and means for adding the sampling frequency indicating codes to the digital signals. Accordingly, sound signals can be recorded and reproduced at various sampling frequencies by the recording and reproducing apparatus of the present invention.
