Patent ID: 7180695

Claim:
A system for writing position information to a rotating medium, comprising: a rotatable medium capable of storing information written to the rotatable medium; a write element capable of writing information to the rotatable medium; and a control mechanism adapted to rotate the rotatable medium and position the write element relative to the rotatable medium, such that the write element can: write a first servo burst during a first servowriting step of the write element over the rotatable medium; trim the first servo burst during a first pass of a second servowriting step of the write element; and write a second servo burst during a second pass of the second servowriting step of the write element, wherein the first servo burst and second servo burst each have a substantially common edge that can be used to determine the position of the write element during a subsequent pass over those servo bursts; wherein the second servo burst can be written before the first servo burst is trimmed.
