An edit mode controller for use in editing magnetic tapes using multiple video tape recorders, in which when one of the recorders is placed in a still or pause mode while waiting for the dubbing location on the other tape to be found, prevents damage to the tape by the repeated scanning of the head in the pause mode by detecting the elapse of a predetermined time period and incrementally advacing the tape by a few number of tracks, then placing the recorder back into the pause mode. The control pulses normally found on video tapes are used to both advance the tape the desired increment and also to rewind the tape back to the desired starting point, once the dubbing point on the other tape has been found.
