Abstract
Official abstract text for this publication.
In one general embodiment, a magnetic head includes an inner module comprising an array of data writers; and first and second outer modules flanking the inner module. The outer modules are identical, each outer module comprising an array of data readers. A number of active data readers in each outer module is less than a number of active data writers in the inner module. For the first outer module, one of the active data readers is aliened with one of the data writers positioned towards a first end of the inner module array in the direction generally parallel to the path of tape travel thereacross. For the second outer module, one of the active data readers is aligned with one of the data writers positioned towards a second end of the inner module array in the direction generally parallel to the path of tape travel thereacross.
