Abstract

본 발명은 SP 모드를 포함한 적어도 두개 이상의 녹화 속도 모드를 갖는 VCR의 오버 랩 방지 방법으로서, 녹화 모드인가를 판단하는 단계와; 녹화 모드이면 자기 테이프를 SP 모드의 속도로 소정 시간 주행시키며 기 기록된 영상 신호를 소거하는 단계와; 소정 시간이 경과하면 기 설정된 녹화 속도 모드에 대응하는 속도로 테이프를 주행시키며 영상 신호를 테이프에 기록하는 단계를 포함한다. 즉, 본 발명은 녹화 모드에서 비데오 헤드와 소거 헤드 사이에 있는 테이프 구간은 녹화 속도 모드에 관계없이 SP 모드로 주행시킨 후에, 기 설정된 녹화 속도 모드에 따라 테이프를 주행시키는 한편 비데오 헤드를 통하여 테이프에 영상 신호를 기록하게 하므로써, 오버 랩 현상을 방지하는 효과가 있다.The present invention provides a method for preventing overlap of a VCR having at least two recording speed modes including an SP mode, comprising: determining whether a recording mode is present; In the recording mode, driving the magnetic tape at a speed of the SP mode for a predetermined time and erasing the previously recorded video signal; Driving a tape at a speed corresponding to a preset recording speed mode when a predetermined time elapses, and recording an image signal on the tape. That is, in the recording mode, the tape section between the video head and the erasing head is driven in the SP mode regardless of the recording speed mode, and then the tape is driven in accordance with the preset recording speed mode while the tape section is driven through the video head. By allowing the video signal to be recorded, there is an effect of preventing the overlap phenomenon.
