ABSTRACT:
Methods are provided for selecting write elements, that can be used in a media-writer, for writing servo burst patterns that have a desired width. Methods for writing preferred servo patterns are also provided. Methods for controlling a write current to produce servo bursts have a desired width are also provided. In accordance with specific embodiments of the present invention, the desired burst width is three-fourths of a data track wide. 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.
