<p>In a method of writing clock data to a storage medium whilst the storage medium is rotating, a burst of clock data is read from a present track. A burst of clock data for a subsequent track on the storage medium is generated in accordance with the burst of clock data read from the present track and its phase adjusted. The phase adjusted burst of clock data is written to the subsequent track. The steps are repeated for plural bursts of clock data around a revolution of the storage medium thereby to write clock data to the subsequent track.</p> |
