Claims (4)

회전 드럼을 구비하고, 이 회전 드럼 주위의 180도의 범위에 기록 매체가 감겨짐과 함께, 영상 신호와 PCM 음성 신호가 시분할 다중화되어서 상기 회전 드럼에 설치된 헤드에서 기록 재생되도록 한 VTR에 있어서, 상기 영상 신호를 상기 회전 드럼의 180도의 회전에 대응하는 소정의 단위 시간마다 시간축 압축함과 함께, 상기한 단위 기간에 대응하는 상기 PCM 음성 신호를 상기 영상 신호의 시간축 압축에 의해 생기는 여백 기간의 길이로 되도록 시간축 압축하여, 이 시간축 압축된 PCM 음성 신호가 상기한 시간축 압축된 영상 신호보다 앞측에 위치하도록 설치하여 상기 시분할 다중화를 행하므로서, 최소한 상기 헤드의 기록 매체로의 돌입부에서 상기 시간축 압축된 PCM 음성 신호의 기록이 행해지도록 한 VTR.A VTR provided with a rotating drum, wherein the recording medium is wound around a range of 180 degrees around the rotating drum, and the video signal and the PCM audio signal are time-division multiplexed so as to be recorded and reproduced in the head provided in the rotating drum. Time-base compression of the signal every predetermined unit time corresponding to 180-degree rotation of the rotating drum, and the PCM audio signal corresponding to the unit period is made to have a length of a margin period generated by time-base compression of the video signal. By time-base compression, this time-base-compressed PCM audio signal is located in front of the time-base-compressed video signal so as to perform the time division multiplexing, so that at least the time-base-compressed PCM voice at the ingress of the head into the recording medium. VTR which allows recording of signals. 상기 PCM 음성 신호는 최소한 2채널씩의 기록 계통이 복수 설치되어, 이들의 계통이 각각 독립의 위치로 되도록 상기 시분할 다중화의 설치가 행해지도록 한 VTR.And a plurality of recording systems of at least two channels are provided for the PCM audio signal, and the time-division multiplexing is performed so that these systems are in independent positions. 제2항에 있어서, 상기 PCM 음성 신호의 각 계통의 위치가 상기 신간축 압축된 영상 신호의 전후에 최소한 1계통 몫 씩 설치되도록 한 VTR.The VTR according to claim 2, wherein the position of each system of the PCM audio signal is provided at least by one system share before and after the new-axis compressed video signal. 제1항, 제2항 또는 제3항에 있어서, 상기 시간축 압축된 PCM 음성 신호의 최단 기록 파장이, 상기 시간축 압축된 영상 신호의 최단 기록 파장보단 길도록 한 VTR.The VTR according to claim 1, 2 or 3, wherein the shortest recording wavelength of the time-base compressed PCM audio signal is longer than the shortest recording wavelength of the time-base compressed video signal. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
