Abstract
A first reader spans first and second tracks of a recording medium and provides a first signal responsive to a first total longitudinal field of the first and second tracks. A second read spans two other tracks, at least one of the two other tracks being different from the first and second tracks. The second reader provides a second signal responsive to a second total longitudinal field of the two other tracks. A third reader spans two or more of the tracks and provides a third signal responsive to a total perpendicular field of the two or more tracks. User data is decoded from the first, second, and third signals.
