Abstract
Systems and methods are disclosed for improving performance in data storage devices, particularly devices employing shingled magnetic recording. In one embodiment, an apparatus may comprise a data storage medium having multiple tracks with multiple track pitches. In another embodiment, a method may comprise formatting a data storage memory with a first track having a first track pitch, and formatting the data storage memory with a second track having a second track pitch. The method may further comprise formatting the computer readable data storage memory with a set of tracks including the first track arranged to store data in a shingled manner where one track at least partially overlaps an adjacent track, and the second track separating the set of tracks from a third track.
