Abstract
A magnetic tape drive has a magnetic head, a magnetic tape medium, and a servo controller. The magnetic head has N servo readers and a plurality of transducing heads for transducing with separate data tracks in each range. The magnetic tape medium is proximate the magnetic head, and has first and second servo tracks and 2N-1 ranges. Each range has a plurality of parallel data tracks. The servo controller, which is responsive to servo read signals produced by two of the servo readers, positions the magnetic head so that the plurality of transducing heads transduce with one of the 2N-1 ranges. Servo read signals produced by one of the N servo readers reading from the first servo track and a different one of the N servo readers reading from the second servo track define one range, while servo read signals produced by two servo readers reading from one of the first and the second servo tracks define 2(N-1) of the ranges.
