A rotary magnetic head type recording and/or reproducing apparatus to which a tracking system can be applied, comprises two rotary heads provided opposing a rotary body for alternately and successively recording signals on oblique tracks in a recording medium with respect to the longitudinal direction of the recording medium or for alternately scanning over tracks in the recording medium to reproduce recorded signals, moving mechanism for continuously moving the recording medium, a head moving mechanism for displacing the two rotary heads substantially at the same time in mutually opposite directions by the same amount in a plane which is perpendicular to the rotating plane of the rotary heads, in response to a driving signal supplied from the exterior, and a control head for recording a control pulse having a predetermined period onto the recording medium. The tracking system comprises a driving signal producing circuit for producing a driving signal from a pulse obtained by detecting the rotation of the rotary body and a control pulse reproduced from the control head, upon reproduction in which the recording medium is continuously moved at a speed different from that upon recording by the moving means and supplying means for supplying the driving signal from the driving signal producing circuit to the head moving mechanism.
