ABSTRACT:
An image signal recording and reproducing system for recording an image signal and an information signal corresponding to the image signal together on a recording medium and for reproducing these recorded signals from the recording medium is arranged to include a power supply circuit which independently supplies power to an information data generating circuit, to detect the power supplied from the power supply circuit to the information data generating circuit, to cause the information data generating circuit to output information data of predetermined contents according to a result of the detection, to record an information signal conforming to the contents of the information data generating by the information data generating circuit on the recording medium along with the image signal, and to make a display conforming to the contents of the information data. This arrangement not only enables the system to prevent any erroneously information signal from being recorded along with the image signal due to consumption of the power supplied from the power supply circuit and also promptly enables the operator to know a consumed state of the electric power of the power supply circuit.
