Abstract
PURPOSE: To prevent an unstable state in the starting of recording and reproduction by allowing a common resetting circuit to reset a video amplifier and audio amplifier in muting mode at the same time.
CONSTITUTION: The circuit consisting of tape 1, video head 2, audio head 3, video amplifier 4, audio amplifier 6, etc., is provided with muting reset dealy circuit 11 in common between amplifiers 4 and 6. When switch 8 is changed over on loading tape 1, amplifiers 4 and 6 in muting mode are reset at the same time after the delay time of the above-mentioned delay circuit 11 passes. In recording and reproduction, video and audio heads are put into operation at the same time in consequence so as to prevent the beginnings of a picture and sound from shifting mutually. In case that tapes are joined together, a dissidence between a picture and sound can be prevented.
