Abstract
Official abstract text for this publication.
Technologies are described herein for cancelling inter-track interference in a storage device utilizing size-adjustable segments. Data is read from one or more sectors on a data track adjacent to a target sector on a target track of a recording medium of the storage device. The target sector is divided into a plurality of segments and data is decoded from the read signal read from each of the segments individually using corresponding data from the one or more sectors of the adjacent track and independent inter-track interference factor values.
First claim
Opening claim text (preview).
What is claimed is: 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 dat…
