Abstract
One embodiment includes positioning a magnetic tape head having at least three servo readers such that a first of the readers is located within a first servo band of a magnetic tape, a second of the readers trailing the first reader is located within the first servo band, and a third of the readers is located within a second servo band of the tape. A lateral position of the head is measured, and a head skew angle is measured. The lateral position and the skew angle of the head are varied while recording y-position values of the first and second readers and the skew angles measured using the first and third readers Nonlinearity values are calculated at discrete y-positions over a range of the servo pattern in the first servo band using at least some of the measured y-positions and skew angle measurements. The nonlinearity values are stored and/or output.
