Abstract
A PCM recording system uses vertical and horizontal synchronizing signals like those of a television video signal, and records PCM sound signal data taking the form of PCM signals converted from a sound signal during specific ones of plural horizontal scanning periods disposed between the vertical synchronizing signals. At least one control signal such as an absolute address signal representing a tape position, an operation indicating signal for indicating the operations such as a tape running stop and a tape rewind and an adjusting signal for adjusting a reproducing system is recorded during the horizontal scanning period with no recording of the PCM sound signal data. At the time of signal reproducing, the control signal is extracted to perform a given display or a given control.
