Abstract
A novel method is used to remap tracks on a disk that contain a defect in a servo field so that a large seek discontinuity is not encountered. The method is applicable to both Class 2 and Class 3 defects. When a track with a Class 2 defect or adjacent tracks with a Class 3 defect are encountered, the tracks are skipped over in assigning physical track numbers to absolute track numbers. When a first defective track is encountered, the next track without a defect is assigned the physical track number that would have been assigned to the first defective track. As the remapping operation continues, each subsequent track with a Class 2 defect or adjacent tracks with a Class 3 defect is handled in a similar manner. The remapping operation is terminated when the number of mapped tracks is equal to the desired number of physical tracks n.
