Abstract
A tape head designed for transducing data on a magnetic recording tape that is subject to tape dimensional changes. The tape head includes two or more arrays of transducer elements having different transducer spacing distances corresponding to different track spacing distances to be transduced. One of the transducer arrays may be used for transducing the tape under nominal tape track spacing conditions. Another transducer array may be used for transducing the tape when the tape track spacing is reduced due to the tape shrinkage. Still another transducer array may be used for transducing the tape when the tape track spacing is enlarged due to tape expansion.
