Abstract:
1. A method comprising steps of: reading data from one or more sectors of an adjacent track of a recording medium, the one or more sectors of the recording medium being adjacent to a target sector on a target track of the recording medium; dividing the target sector into a plurality of segments; determining a first inter-track interference factor value for a first segment of the plurality of segments based on a read signal from the first segment and the data from the one or more sectors of the adjacent track; decoding data from the read signal read from the first segment using the first inter-track interference factor value; determining a second inter-track interference factor value for a second segment of the plurality of segments based on a read signal from the second segment and the data from the one or more sectors of the adjacent track, the second inter-track interference value independent of the first inter-track interference value; and decoding data from the read signal read from the second segment using the second inter-track interference factor value.
