In a track-following servo system for a magnetic disk file, buried-serv information is recorded with the record head gap aligned parallel to a tangent to the disk, thus creating a radial field instead of the conventional tangential field. The servo information is then read with the servo read head gap aligned tangentially. Data is written and read with head(s) gap aligned radially in the conventional manner.
