The amount of position error written into a servo burst pattern can be
reduced by using additional media revolutions to write the pattern. Where
the edges of two servo bursts are used to define a position on the media,
trimming the first burst and writing the second burst on separate
revolutions will result in a different amount of position error being
written into each burst. The end result will be a reduction in the
overall error in position information. In order to further reduce the
position error given by a burst pair, each burst also can be trimmed
and/or written in multiple passes. Additional bursts can also be written,
such as for each data track centerline. This description is not intended
to be a complete description of, or limit the scope of, the invention.
Other features, aspects, and objects of the invention can be obtained
from a review of the specification, the figures, and the claims.
