For precise positioning of a magnetic head to various tracks of a magnetic tape, deviations occur as a consequence of manufacturing tolerances of the magnetic head, or as a consequence of the adjustment thereof. Correction values are identified wherein a read head identifies a center of a track recorded by a write head. A moving direction of the magnetic tape is reversed and the center of the track is identified again. The read head identifies the center of a track recorded by a neighboring write head. Positional values allocated to the center of the tracks are subtracted from the positional value of the write head.
