Abstract
Method and apparatus for positioning shingled magnetic recording (SMR) tracks on a rotatable data storage medium. In some embodiments, a first band of partially overlapping tracks is written the medium at a first track pitch. An adjacent, second band of partially overlapping tracks is written to the medium at the first track pitch. The second band has a first written track at a second track pitch with respect to a last written track in the first band. The second track pitch is determined in response to an error rate established for a test track using an adjacent track written at the first track pitch.
