机译:用于记录视频信息信号以避免在后记录期间发生干扰的方法和设备

摘要

Video and information signals are recorded in slant tracks on a magnetic tape having a wrap angle of no more than about 180° by timebase converting at least the video signal which then is time division multiplexed with the information signal. The time division multiplexed signals are recorded sequentially in a length of track that is less than the wrap angle to form successive tracks.
