A capstan servo system for a video tape recording and/or reproducing apparatus permits recording of a new video signal precisely commenced at a selected edit point. For this, the capstan servo system is provided a tape speed error dependent feedback control feature and a phase error dependent feedback control feature. Tape speed error dependent feedback control is carried out when the recording and/or reproducing apparatus operates in recording or assemble edit mode. Phase error dependent feedback control is carried out when the recording and/or reproducing apparatus operates in reproducing or playback mode.
