装置におけるドロップアウト補償装置。In a multi-channel magnetic recording and reproducing device that performs multi-channel recording and reproduction by dividing a color video signal into each color signal, a dropout detector is provided on each signal line of each channel of the reproduction system, and a dropout compensation circuit is also provided. Each dropout compensation circuit is operated by the OR output of each detection signal from each dropout detector, and when a dropout occurs in any one signal of each channel of the reproduction system, all of the signals of each channel are 1. A dropout compensation device for a multi-channel magnetic recording/reproducing device, characterized in that the dropout compensation circuits are configured to operate simultaneously.
