Claims (1)

Y/C신호 처리회로(1)와 Y/C혼합부(2)를 통해 인가된 비디오 신호를 증폭하여 4개의 헤드(CH1~CH4)로 각각 인가하는 병렬 구성된 4개의 기록앰프(REC1~REC4)와, 상기 기록 앰프(REC1~REC4)의 입력단에 연결되며 기록용 스위칭 제어신호(SW1~SW4)에 의해 온/오프되는 스위치(S1,S5,S9,S13)와 상기 기록 앰프(REC1~REC4)의 출력단에 연결되며 재생신호(PB)와 재생용 스위칭 제어신호(SW1'~SW4')에 의해 온/오프되는 스위치(S2, S6, S10, S14)와 상기 헤드(CH1~CH4)의 신호를 받아 증폭하여 Y/C신호처리회로(3)를 통해 비디오 신호 출력하는 프리앰프(PRE1~PRE4)와, 상기 프리 앰프(PRE1~PRE4)의 입력단에 연결되고 오아게이트(01~04)를 통해 인가되는 기록신호(REC)와 기록용 스위칭 제어신호(SW1~SW4)에 의해 온/오프되는 스위치(S3, S7, S11, S15)와 기록용 스위칭 제어신호(SW1'~SW4')에 의해 온/오프 동작하여 상기 스위치(S3, S7, S11, S15)의 온/오프를 제어하는 스위치(S4, S8, S12, S16)를 포함하여 구성된 것을 특징으로 하는 동시 녹화 재생·장치.Four recording amplifiers REC1 to REC4 configured in parallel to amplify the video signals applied through the Y / C signal processing circuit 1 and the Y / C mixing section 2 and apply them to the four heads CH1 to CH4, respectively. And switches S1, S5, S9, and S13 connected to the input terminals of the recording amplifiers REC1 to REC4 and turned on / off by the recording switching control signals SW1 to SW4, and the recording amplifiers REC1 to REC4. The signals of the switches S2, S6, S10, and S14 and the heads CH1 to CH4, which are connected to an output terminal of the switch and are turned on / off by the reproduction signal PB and the reproduction switching control signals SW1 'to SW4'. It is connected to an input terminal of the preamps PRE1 to PRE4 for receiving and amplifying and outputting a video signal through the Y / C signal processing circuit 3, and is applied through an oragate (01 to 04). ON / OFF by the switches S3, S7, S11, and S15 and recording switching control signals SW1 'to SW4' which are turned on / off by the recording signal REC and the recording switching control signals SW1 to SW4. By above operation And a switch (S4, S8, S12, S16) for controlling on / off of the switches (S3, S7, S11, S15). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
