A two-step self-servowriting process first writes an intermediate pattern
based on a reference pattern, and then writes a final pattern based on
the intermediate pattern, wherein the reference pattern can be a printed
media or a spiral pattern. Such an approach can be utilized to reduce the
noise/runout, eliminate timing eccentricity, and increase the sample rate
of the final pattern. 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.
