Patent ID: 6995940

Claim:
A system to write a target track of servo information to a rotatable storage medium using a reference track of servo information, comprising: a write element adapted to write servo information to the rotatable storage medium; a control mechanism adapted to control writing of servo information to the rotatable storage medium, the control mechanism to: enable writing of servo information to the target track of the rotatable storage medium by the write element during one or more revolutions of the rotatable storage medium, wherein writing servo information is inhibited when a location of the write element is not within a first threshold distance of a desired location, and wherein writing servo information is resumed after the location of the write element is determined to be within a second threshold distance; determine WORF data from the reference track of servo information during the one or more revolutions; and enable writing of servo information not written to the target track during the one or more revolutions during a subsequent revolution using the WORF data.
