The frequency modulator and demodulator of the DC signal were made by using phase locked loop IC. The usual audio tape-recorder connected with the adaptors could record and reproduce the DC signal as like the instrumentation tape-recorder. The drift, distortion ratio, and the linearlity of the output of the recorder were measured. The ratio of the signal to noise (S/N), output noise and the output voltage of the recorer were 55dB, 1mV, and 0.6V r. m. s., respectively. These values were similar to those of the instrumentation tape-recorder.
