Abstract
Methods and apparatus are disclosed for writing and verifying servo frames written on a storage medium, for verifying data areas of a storage medium, and for writing and verifying servo frames and data areas of a storage medium. In one example, the writing of at least a portion of a position field of a servo frame to a track of the storage medium is interleaved with reading of at least a portion of a previously written logic field of a servo frame of a track of the storage medium whereby said portion of the previously written logic field can be verified during the servo writing process.
