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.
