ABSTRACT:
A reference track is recorded in a longitudinal direction on a recording medium. During recording of an information signal along parallel tracks on the medium a deviation of the reference track in a transverse direction from its nominal position with respect to the medium transport is detected by one or more sensor heads mounted in a fixed relationship with respect to the medium transport. A positionably mounted data head is moved in transverse direction in accordance with the sense and magnitude of the detected deviation, thereby maintaining the data head in a known geometric relationship with the reference track during the recording process. During playback the same reference track may be utilized to follow the thusly recorded parallel tracks.
