Tape heads and controllers for controlling such heads in a tape drive are described. A controller may determine a first parameter corresponding to the similarity between data read by a first pair of read elements of a head, a second parameter corresponding to the similarity between data read by another pair of read elements having one read element in common with the first pair, and a position of the head with respect to a data track based upon a relationship between the first and second parameters. The controller may adjust the head to a proper lateral position based upon the determined position.
