Disk-locked loop in self-servo-write using spiral sync-mark detection |
摘要 |
Writing servo wedge code to a disk is disclosed. A wedge-to-wedge time interval is determined. At least until it is determined that a lock criterion is met: For each wedge-to-wedge time interval, a wedge frequency error is computed based on an adjustable clock. The clock is adjusted based on one or more of the wedge frequency errors. It is determined whether a lock criterion is met based on one or more of the wedge frequency errors. After the lock criterion is met, servo wedge code is written to the disk.
