Abstract
Technologies are described herein for cancelling adjacent track interference in a storage device using an ITI predictor determined from predetermined data patterns in adjacent tracks. A first signal is read from a first portion of a data track, the first portion containing a first predetermined data pattern. Next, a value for an inter-track interference predictor associated with an adjacent track is determined based on the first signal, the first predetermined data pattern, and a second predetermined data pattern contained in a corresponding portion of the adjacent track. A second signal is read from a second portion of the data track, and inter-track interference from the adjacent track in the second signal is cancelled utilizing the value for the inter-track interference predictor.
