摘要： Various embodiments of the present invention provide systems and methods for data processing. As an example, a data processing circuit is discussed that includes: a data buffer, an inter-track interference response circuit, an inter-track interference signal estimator circuit, and a sync mark detector circuit. The data buffer is operable to store a previous track data set that includes a first sync pattern. The inter-track interference response circuit is operable to estimate an inter-track interference response from the previous track data set based at least in part on the previous track data set and a current track data set. The current track data set includes a second sync pattern. The inter-track interference signal estimator circuit is operable to calculate an inter-track interference from the previous track data set based at least in part on the previous track data set and the inter-track interference response from the previous track data set. The sync mark detector circuit operable to identify the first sync pattern in the inter-track interference from the previous track data set in the current track data set.
