Abstract

PURPOSE:A rotation control mechanism is simplified by recording a high frequency single signal having a synchronizing or offset relation with a horizontal synchronizing signal on one circumferece of rotaty recording disc and applying servo of a horizontal synchronizing mode through frequency division of this reproduction signal in an apparatus of recording TV signals in a rotary magnetic recording medium such as magnetic discs.
