Abstract
A disk drive is disclosed comprising a disk comprising a plurality of data tracks, and a head comprising a first read element and a second read element. The first read element is positioned over a first data track and the second read element is positioned over a second data track. A first analog read signal emanating from the first read element is adjusted based on a second analog read signal emanating from the second read element in order to reduce noise in the first analog read signal due to interference from the second data track.
