When the key is pressed, the key input unit 10 for outputting data on the key and the key data of the key input unit 10 are scanned, and the audio / video signal processing unit 30 is controlled according to the data, and the predetermined capstan A central processing unit (20) for outputting the driving data of the motor (70) to the servo circuit unit (60) and setting and storing and reading a predetermined time value while checking whether or not the vertical synchronous signal is input from the predetermined vertical synchronous signal detector (50); Outputs image and audio signals by inputting image and audio control signals output from the central processing unit 20, and also receives playback signals from the audio / video head 40. The video signal processor 30 and the video signal processor 30 to record a recording signal on a VTR tape and to read and output a signal recorded on the VTR tape. A vertical synchronous signal detection unit 70 for detecting a vertical synchronous signal from the reproduction signal of the video / video head 40 and outputting a predetermined pulse when the signal is present; and the capstan motor ( 70) the servo circuit unit 60 receiving the drive data to drive the capstan motor 70, the capstan motor 70 driven under the control of the servo circuit unit 60, and the central processing unit 20 And a storage device (80) for temporarily storing the set time value. 사용자가 코드 키입력부(10)을 통해 소정 녹화키를 한번 누르면 녹화되고 두번 누르면 전술한 녹화에서 소정 VTR 테이프상의 녹화되지 않은 부분을 찾아 그곳에서 소정간격 뒤부터 녹화하는 비디오 테이프 레코더의 테이프의 자동탐색 녹화방법에 있어서, 녹화키가 입력되는가 점검하는 제1과정과, 상기에서 녹화키가 입력되면 녹화모드 신호를 출력하고 이어서캡스턴 모타 구동신호를 출력한 뒤 다시 녹화키가 입력되는가 점검하는 제2과정과, 상기 제2과정에서 녹화키가 입력되지 않으면 정지키가 입력되는가 점검하여 정지키가 입력될때 상기 출력하는 녹화모드 신호를 차단하고 종료하는 제3과정과,상기 제2과정에서 녹화키가 입력되면 상기 녹화모드 신호 차단후 찾음 모드신호를 출력하고 수직동기 신호가 입력되는가 점검하는 제4과정과, 상기 수직동기 신호입력을 점검하는 과정에서 수직동기 신호가 입력되면 테이프의 끝인가 판단하여 테이프의 끝이면 상기 단계에서 출력하기 시작한 모타구동 신호 및 찾음모드 신호의 출력을 중단하고 테이프이 끝이 아니면 상기 제4과정의 수직동기 신호입력을 점검하는 단계(280)로 진행되는 제5과정과, 상기 제4과정에서 신호의 입력이 없으면 소정시간을 세팅한 뒤 그 시간만큼 지연한 뒤 상기 제2과정의 녹화모드 신호 출력단계(220)로 진행되는 제6과정으로 이루어짐을 특징으로 하는 방법.When the user presses the predetermined recording key once through the code key input unit 10, the recording is performed. When the user presses the recording key twice, the tape of the video tape recorder which finds the unrecorded part on the predetermined VTR tape in the above-described recording and records thereafter from the predetermined interval thereafter. In the recording method, a first step of checking whether a recording key is input and a second step of checking whether a recording key is input again after outputting a recording mode signal when the recording key is input, followed by outputting a capstan motor driving signal. And a third step of checking whether the stop key is input if the recording key is not input in the second step, and blocking and terminating the output recording mode signal when the stop key is input; and inputting the recording key in the second step. And a fourth process of outputting a search mode signal after checking the recording mode signal and checking whether a vertical synchronization signal is input. In the process of checking the synchronization signal input, if the vertical synchronization signal is input, it is determined that the end of the tape, and if the end of the tape, the output of the motor drive signal and the search mode signal started to be output in the above step is stopped, and if the tape is not the end, the fourth process The fifth step proceeds to the step 280 of checking the vertical synchronization signal input of the step, and if there is no signal input in the fourth step, after setting a predetermined time and delayed by that time, the recording mode signal of the second step And a sixth process proceeding to an output step (220). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
