Abstract
PURPOSE: To prevent the occurrence of cross talk as much as possible without limiting the recording-dedicated band of video signals, by bringing the time-division recording of audio signals and video signals to effect.
CONSTITUTION: In each horizontal blanking interval H-BLK (about 11μS) of video signals, the time-dividing multiple recording of FM autio signals AL and AR of two channels comes into effect. Here, audio signals AL and AR are intermittently recorded in horizontal blanking H-BLK being time-compressed and restored into a continous signal in reproduction. Since luminance signals and recording FM audio signals are time-divided mutually, cross talk can be avoided even by overlapping bands of FM audio signals AL and AR with the lower side-band (higher side of luminance signal) of FM luminance signal Y-FM. The deviation frequency of FM luminance signal Y-FM can therefore be lowered and the recording-dedicated band can be used more effectively.
