이를 위해 본 발명은, 키입력부(70)로부터의 키입력신호에 따른 마이콤(30)의 제어에 의해 CD에 기록된 데이터를 광학적으로 독출하고 이 독출된 RF 신호를 증폭한 다음 디지탈신호처리부(41)에 의해 디지탈신호 처리된 디지탈음성데이터를 디지탈/아날로그변환부(15)에 의해 아날로그신호로 변환하고 로우패스필터(16)를 거치면서 L 채널과 R 채널로 분리한 후 상기 마이콤(30)의 제어에 따라 CD 모드의 VCR 모드로 절환되는 오디오출력셀렉터(20)를 거쳐 스피커로 출력하는 CD 플레이어와, 상기 키입력부(70)로부터의 재생 및 녹화기능입력신호에 따른 상기 마이콤의 제어에 의해 비디오테이프에 저장된 데이터를 독출/증폭하여 영상/음성처리부(40, 50)에 의해 영상/음성처리하여 도시되지 않는 모니터 및 스피커로 출력하거나 또는 튜너로부터의 텔레비전영상/음성신호나 외부입력단자에서 입력되는 영상/음성신호를 상기 영상/음성처리부(40, 50)에 의해 처리하여 비디오테이프에 녹화하는 VCR의 복합구성되어 있는 CD 플레이어와 VCR의 복합제품에 있어서; 상기 마이콤(30)에는 키입력부(70)로부터 오디오더빙모드가 선택됨에 따라 제3스위칭수단(60)으로 소정의 제어신호를 송출하여 단락시킴과 더불어 제2스위칭수단(52)에도 소정의 제어신호를 송출하여 CD 신호입력모드로 스위칭절환하고, 제1 및 제2오실레이터(32, 31)중 제2오실레이터(31)에 소정의 제어신호를 송출하여 제2오실레이터(31)를 구동시켜 오디오소거헤드(61)만을 동작시킴으로써, CD 플레이어와 VCR은 재생모드로 동작되면서 상기 CD 플레이어의 로우패스필터(16)를 거치면서 분리된 L 채널음성정보만을 비디오테이프의 오디오트랙에 기록하도록 하는 기능이 더 구비되어 있다.To this end, the present invention, by controlling the microcomputer 30 according to the key input signal from the key input unit 70, optically reads the data recorded on the CD and amplifies the read RF signal, and then the digital signal processor 41 The digital audio data processed by the digital signal is converted into an analog signal by the digital / analog converter 15 and separated into an L channel and an R channel through a low pass filter 16, and then The CD player outputs to the speaker via the audio output selector 20 switched to the VCR mode of the CD mode under control, and the video is controlled by the microcomputer according to the playback and recording function input signals from the key input unit 70. Read / amplify the data stored on the tape, and output the image / audio by the image / audio processing unit 40 or 50 to output to a monitor and a speaker (not shown) or a television image / sound from a tuner. In the video / audio signal input from the signal or an external input terminal to the composite product of the video / audio processing CD player and a VCR that is treated by (40, 50) configured compound of the VCR to be recorded on a video tape; As the audio dubbing mode is selected from the key input unit 70, the microcomputer 30 transmits a predetermined control signal to the third switching means 60 to short-circuit the predetermined signal. To switch to the CD signal input mode, send a predetermined control signal to the second oscillator 31 among the first and second oscillators 32 and 31 to drive the second oscillator 31 to drive the audio erasing head. By operating only 61, the CD player and the VCR are operated in a playback mode, and further have a function of recording only the separated L channel voice information on the audio track of the videotape while passing through the low pass filter 16 of the CD player. It is.
