Abstract
본 발명은 VCR테이프에 기록되는 REC-Y 신호 및 REC-C 신호를 자동으로 가변되도록 하여 기록 전류 조정을 자동으로 실현할 수 있도록 한 VCR의 기록 전류 자동 조정회로에 관한 것으로, 종래에는 기록 전류를 수동으로 조정하므로 부정확하고 입력 비디오 신호의 레벨에 따라 기록전류가 변동하는 결점이 있었으나, 본 발명에서는 REC-Y 신호 및 REC-C 신호를 자동으로 가변할 수 있는 회로를 각각 구성하여 기록 전류 조정을 자동으로 할 수 있도록 하므로써 상기 결점을 개선시킬 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording current automatic adjustment circuit of a VCR that automatically realizes recording current adjustment by automatically varying the REC-Y signal and the REC-C signal recorded on the VCR tape. Although it was inaccurate and the recording current fluctuated according to the level of the input video signal, the present invention configures a circuit capable of automatically varying the REC-Y signal and the REC-C signal. By making it possible, the above-mentioned defect can be improved.
