Abstract:
In a servowriting system for implementation in a storage device including a storage medium and a transducer positionable relative to the storage medium under the control of a servo system for writing position information to the medium, the storage device subsystem having a set of operating parameters, a method for reducing input noise introduced into written position information in a servowriting process, caused by at least one of said operating parameters, comprising the steps of:writing first servo position information comprising at least one track, each track having a sector including position information, as part of the servowriting process; measuring an indicium of said input noise introduced into the first written position information; and optimizing, based on said measured indicium of said input noise, at least one operating parameter of the storage device subsystem so as to reduce said input noise and reduce resultant compounded errors in subsequently written position information.
