生装置。[Claims for Utility Model Registration] Recording signals are helically recorded on a magnetic tape by a rotating head provided on a rotating drum, and based on a reference predetermined signal having information on the formed recording track or the reference predetermined signal. The formed control signal is delayed according to the position of a control head provided outside the rotating drum, and the control signal having a predetermined phase relationship with respect to the reference predetermined signal is applied to the magnetic tape by the control head. In a magnetic recording and reproducing device for recording on a magnetic recording device, during reproduction, the control servo device generates the control signal formed and delayed based on the reference predetermined signal or the delayed reference predetermined signal and the control servo device that is picked up by the control head. 1. A magnetic recording and reproducing apparatus, wherein running of the magnetic tape is controlled according to a phase difference between the picked-up control signal or the predetermined signal reproduced from the picked-up control signal.
