Abstract
A head unit for use in a helical scan magnetic tape drive comprises a substrate having a substrate surface (300) and multiple thin film magnetic elements (D.sub.1, D.sub.2) formed on the substrate. Each of the multiple thin film magnetic elements has an interactive component for transducing information with respect to magnetic tape. The interactive components of at least two elements are situated on different planes at respective different distances from the substrate surface. None of the multiple elements of the head unit are situated to traverse a same path on the magnetic tape. Moreover, all of the multiple elements of the head unit perform a same type of transducing operation.
