ABSTRACT:
A hard disk drive with a disk that has a plurality of data fields. Each data field includes a sync field and a plurality of sync marks. Data is written onto the disk in accordance with a write clock. The write clock is generated and synchronized by the sync field and the sync marks. The sync marks are dispersed throughout the data field so that the write clock is resynchronized as data is written onto the field.
