RADIAL SELF-PROPAGATION PATTERN GENERATION FOR DISK FILE SERVOWRITING

摘要

During a write revolution of a storage medium, a transition is written on th e storage medium while servoing on another transition previously recorded on the storage medium. During that write revolution, a position error signal corresponding to the position error of t he transducer relative to the previously recorded transition is determined. That position error signal is then stored, during the write revolution, to be used in computing a reference track value associated with the transition being written to correct for the position error. Additionally, a product servo- pattern is written, which includes an embodying of the position error therein.
