DETECTION OF ADJACENT TRACK INTERFERENCE USING SIZE-ADJUSTABLE SLIDING WINDOW

摘要

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.

1. A method comprising steps of:
determining a value for an inter-track interference factor associated with at least one adjacent track in a first area of a data track, the first area comprising a plurality of sectors of the data track; determining whether the value of the inter-track interference factor is greater than a threshold; and upon determining the value of the inter-track interference factor is greater than the threshold, storing an inter-track interference indicator corresponding to the first area.
