ABSTRACT OF THE DISCLOSURE A servo system for positioning a data transducer head relative to a plurality of substantially concentric data tracks on the surface of a magnetic disc including a pair of servo transducer heads for sensing the data tracks and generating output signals representative of a data signal written on the sensed track, a distance between the pair of servo transducer heads being related to the dimension of the data track and a distance between the servo transducer heads and the data transducer head being related to a data track pitch, a signal processing circuit connected to the pair of servo transducer heads for generating a data transducer head positioning signal and a positioning device for positioning the data transducer head in response to the transducer positioning signal and for maintaining the track centerline alignment of the data transducer head.
