Principal embodiment teaches method and apparatus for fine positioning (centering) of a magnetic recording transducer relative to the concentric tracks of a rotatable magnetic disk having an "embedded" format (i.e., work data and servo data interspersed in alternate sectors along each track - vs. "dedicated servo tracks"). The servo data sectors comprise repeating groups of servo tracks used to provide coarse and fine radial positioning signals for the transducer relative to the work data tracks.
