Abstract
A disk drive is disclosed comprising a disk comprising a plurality of tracks, and a head comprising at least three read elements including a first read element, a second read element, and a third read element. When the head is within a first radial band of the disk, data recorded on the disk is detected using the first read element and the second read element. When the head is within a second radial band of the disk different from the first radial band, data recorded on the disk is detected using the first read element and the third read element. The first read element is substantially aligned down-track with the third read element when the head is over a first radial location of the disk.
