Abstract
A system including an analog front end module to receive a first signal generated by reading data from a storage medium storing the data in concentric tracks, sample the first signal, and output a second signal based on the sampling of the first signal. An equalizer module generates a first vector based on the second signal. The first vector represents the data in the first signal. A detector module generates a second vector based on the first vector. The second vector represents a noise-free vector corresponding to the first vector. A re-timing module re-samples a plurality of samples in the first vector based on the second vector and generates a third vector based on the re-sampling of the plurality of samples in the first vector. An inter-track interference cancellation module removes inter-track interference from the third vector.
