Title: Method and apparatus for initial self-servo writing

Abstract: Embodiments of the present disclosure provide a method of self-servo writing, the method comprising actions of positionally tracking a selected timing track of a data storage disk, wherein the selected timing track has one or more timing segments; synchronizing an angular position signal to rotation of the data storage disk based on at least one of the one or more timing segments of the selected timing track; specifying servo sector positions relative to the synchronized angular position signal; writing servo sectors to the data storage disk at the specified servo sector positions relative to the synchronized angular position signal; detecting one or more positional errors in timing segments of a next timing track of the data storage disk based at least in part on the synchronized angular position signal; and accounting for the detected one or more positional errors in writing subsequent servo tracks. Other embodiments are also described.
