ABSTRACT:
A disc drive device where data and servo position information is stored in data segments on concentric tracks on the disc surface. The servo position information indicates the track centerline for each data segment. The offset of the servo position information from an ideal track centerline for each track is measured and stored into memory. The read/write head, which accesses data on the disc tracks, is positioned over the track centerline based on the offset for each data segment.
