ABSTRACT:
A PCM type record-playback system converts an analog primary signal into a digital signal by sampling and quantizing it and concurrently records it on a magnetic tape with a secondary signal for showing the tape position. The primary and secondary signals are recorded on the same track in a time-divided manner so that recording can be effected with a small number of magnetic heads and the tracks on the magnetic tape can be effectively utilized.
