Abstract
PURPOSE: To ensure recording for both the voice and time onto one channel by cutting the low frequency band by the filter at the recording time and then modulating the time signal to the frequency within the low frequency band.
CONSTITUTION: Recording circuit 10 consists of low cut filter 13, recording amplifier 12 and recording head 11 each. And means 14 which generates time display signal TS of the low frequency is connected in parallel to filter 13 at the input side of amplifier 12. With supply of aural input VI, the low range of the voice is cut by filter 23. And the voice is sent to amplifier 12, and at the same time means 14 transmits signal TS within the low frequency band to amplifier 12. Receiving both aural signal VS and time display signal TS, amplifier 12 records these two signals onto the same channel of the tape through head 11. Thus the time can be recorded onto one aural channel together.
