1. An inter-track interference compensation system, the system comprising:
a data buffer operable to store a previous track data set as a series of multi-bit digital samples, wherein the previous track data set includes: a new component and an old component, wherein the old component is stored on a storage medium between the new component of the previous track data set and a current track data set; an inter-track interference generation circuit operable to generate an inter-track interference from the previous track data set on the current track data set, wherein the inter-track interference includes a first interference component corresponding to the new component and a second interference component corresponding to the old component.
