Abstract:
1. A method, comprising: receiving an input sequence of samples associated with a track on magnetic storage; using a processor to generate inter-track interference (ITI) data associated with a first side track including by performing a correlation between the input sequence of samples and a sequence of data associated with the first side track; generating ITI data associated with a second side track, including by performing a correlation between the input sequence of samples and a sequence of data associated with the second side track; removing the ITI data associated with the first side track and the ITI data associated with the second side track from the input sequence of samples; determining that error correction processing, associated with the input sequence of samples with the ITI data associated with the first side track and the ITI data associated with the second side track removed, has failed; and generating a new position associated with a read-head based at least in part on a power value associated with the ITI data associated with the first side track and a power value associated with the ITI data associated with a second side track.
