Abstract: Detecting track information involves receiving first and second overlapping track signals from first and second read elements that read first and second tracks from a data storage medium. Information of the first and second tracks is estimated using the respective first and second track signals. An improved information estimate of the first track is obtained using the first track signal and the estimated information of the second track, and an improved information estimate of the second track is obtained using the second track signal and the estimated information of the first track. First and second track data are decoded using the respective improved information estimates of the first and second tracks.

Abstract: A system can include a first buffer storing a first fragment of data for a first data sector in a first track of a storage medium, a second buffer storing a second fragment of data for a second data sector in a second track of the storage medium adjacent to the first track, a processor configured to determine an estimated region of overlap between the first data fragment and the second data fragment, and a circuit configured to refine the estimated region of overlap by determining an offset value to offset an estimated beginning portion of overlap by the second fragment.
