Zusammenfassung:	PROBLEM TO BE SOLVED: To provide advanced systems and methods for inter-track interference compensation.SOLUTION: In reading back from a storage medium such as a hard disk, inter-track interference from the previous track data set on the current track data set is estimated or calculated, and a cancellation circuit 330 subtracts the inter-track interference from the current track data set to yield a corrected output.
