Abstract
A hard disk drive or other disk-based storage device comprises a storage disk, a read/write head configured to read data from and write data to the storage disk, and control circuitry coupled to the read/write head and configured to process data received from and supplied to the read/write head and to control positioning of the read/write head relative to the storage disk. The control circuitry comprises an inter-track interference detector configured to process a signal read from at least a given track of the storage disk via the read/write head in order to detect interference in that signal from at least one other track of the storage disk. The control circuitry further comprises an inter-track interference based head position controller configured to adjust the positioning of the read/write head responsive to the detected interference.
