Patent ID: 6999264

Claim:
A method for writing position information to a rotatable medium, comprising: selecting a pattern comprising a plurality of concentric tracks, wherein each concentric track is defined by a plurality of burst boundaries positioned circumferentially about a rotatable storage medium, the rotatable storage medium having an inner diameter and an outer diameter; writing a first servo burst and a second servo burst for each burst boundary to the rotatable storage medium, wherein the first servo burst and second servo burst are written on separate passes of a write element over the rotatable storage medium, and wherein the first servo burst and second servo burst each have an edge that can be used to determine the position of the write element during a subsequent pass over those servo bursts; and trimming the first servo burst for each burst boundary, wherein a subset of the plurality of concentric tracks is selected wherein the burst boundaries defining that subset use a separate pass of the write element to trim the first servo burst, the subset being selected based upon the proximity of each concentric track to at least one of the inner diameter and outer diameter.
