Abstract

PURPOSE:To eliminate the unpleasant noise, by recording both the analog and digital signals on the same track and controlling the signal output when the digital signal is reproduced. CONSTITUTION:The detection signals for the positions by both the digital and low frequency signals are recorded on the same track of a magnetic tape on which the analog signal is recorded. Then the output of the analog signal is controlled based on the detection of the detection signal and when the digital is reproduced. For instance, when the tape comes to the recorded position of the digital signal, the low frequency signal is detected by an LPF20 to be transmitted to a CPU. Then the muting is applied to the acoustic output. Meanwhile the digital signal is transmitted to the CPU via a demodulating circuit to be displayed in the form of a character train.
