Claims (1)

자기테이프상에 경사지게 형성된 기록 트랙을 회전자기헤드에 의해서 주사해서 재생 신호를 얻도록한 자기 기록 재생장치에 있어서, 상기 회전자기헤드에서 출력되는 재생 고주파 신호의 레벨의 증감을 판별하는 신호 레벨 판별수단과, 상기 신호 레벨 판별 수단의 판별 출력에 기준해서 상기 자기테이프의 주행 속도를 제어하는 수단과, 트래킹 에러에 대한 재생 고주파 신호의 레벨변화의 비선형성을 보정하기 위한 이득 보정 수단을 구비한 것을 특징으로 하는 자기기록 재생장치.A magnetic recording and reproducing apparatus which scans a recording track formed obliquely on a magnetic tape with a rotating magnetic head to obtain a reproduction signal, comprising: signal level discriminating means for discriminating the level of the reproduction high frequency signal output from the rotating magnetic head; And means for controlling the traveling speed of the magnetic tape on the basis of the discrimination output of the signal level discriminating means, and gain correction means for correcting the nonlinearity of the level change of the reproduction high frequency signal with respect to the tracking error. Magnetic recording and reproducing apparatus. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
