SYSTEM AND METHODS FOR COMBINING MULTIPLE OFFSET READ-BACKS

Techniques for processing signals read-back from a disk of a hard disk drive are described. In one example, a hard disk drive device generates a signal associated with a first position within a width of the data track. The first position may correspond to the center of a data track. The hard disk dr...

Zusammenfassung:Techniques for processing signals read-back from a disk of a hard disk drive are described. In one example, a hard disk drive device generates a signal associated with a first position within a width of the data track. The first position may correspond to the center of a data track. The hard disk drive device generates a signal associated with a second position within a width of the data track. The second position may be located at a distance of approximately 10% of the track width from the track center. The hard disk drive device combines the signals and applies as signal conditioning technique to the combined signal.
