Detection of adjacent track interference using size-adjustable sliding window

A non-transitory computer-readable storage medium having processor-executable instructions stored thereon that, when executed by a processor, cause the processor to:

• determine a value for an inter-track interference factor associated with at least one adjacent track in a first area of a data track of a storage device, wherein the first area encompasses a plurality of sectors of the data track;
• determine whether the value of the inter-track interference factor is greater than a threshold value;
• and
• upon determining the value of the inter-track interference factor is greater than the threshold value, store an indication of inter-track interference corresponding to the first area, the indication of inter-track interference comprising an indication of inter-track interference from the at least one adjacent track in the first area of the data track, wherein the indication of inter-track interference corresponding to the first area is utilized to compensate for inter-track interference from the at least one adjacent track during a read of a sector within the first area of the data track.

A system comprising:

• a hard disk drive comprising a storage medium;
• a processor operably connected to the hard disk drive;
• and
• an ITI detection module operably connected to the processor and configured to cause the processor to
• determine a value for an inter-track interference factor associated with at least one adjacent track in a first area of a data track of the storage medium,
• determine whether the value of the inter-track interference factor is greater than a threshold value, and
• upon determining the value of the inter-track interference factor is greater than the threshold value, store an indication of inter-track interference corresponding to the first area in a memory of the hard disk drive, the indication of inter-track interference comprising an indication of inter-track interference from the at least one adjacent track in the first area of the data track, wherein the stored indication of inter-track interference corresponding to the first area is utilized by a controller of the hard disk drive to compensate for inter-track interference from the at least one adjacent track during a read of data from the first area of the data track.
