ABSTRACT:
Wedge Offset Reduction Field (WORF) data can be used to reduce the effective written-in runout of a servo pattern. In order to prevent the WORF data from being applied to an improper portion of the servo pattern, the identification of a quadrant associated with that WORF data can be stored with the WORF data. For example, the servo pattern of a hard disk can contain a number of servo burst boundaries. In order to ensure that the WORF data is applied to the proper burst boundary, the identity of a quadrant associated with that boundary can be written into the servo wedge along with the WORF data. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
