Technologies are described herein for detecting adjacent track interference in a storage device using a size-adjustable sliding window. A value for an inter-track interference factor associated with at least one adjacent track is determined for a first area of a data track of the storage device. The first area may encompass a plurality of sectors of the data track. Next, it is determined whether the value of the calculated inter-track interference factor is greater than a threshold value, and if so, an indication of inter-track interference corresponding to the first area is stored in the storage device.

Detection of adjacent track interference using size-adjustable sliding window

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.
