ABSTRACT:
In a video tape recorder of a helical scan type, a low frequency index signal and a high frequency signal are simultaneously applied to a full erase head (FE) with the high frequency signal acting as a bias prior to the recording of a video program. After the index signal has been recorded, the application of the high frequency signal is continued to erase a prerecorded material. The high frequency biasing prevents the index signal from interfering with the video signal during playback.
