N2 - Among the many problems in the Self-servo Track Writer (SSTW), the error propagation problem is discussed in this paper. To deal with the error propagation problem, we take two approaches: estimation of the absolute head position and reference correction design using the Position Error Signal (PES) in the previous track. To improve the estimation of absolute position of the head with regard to the whole disc, Kalman filter is designed and removes the estimation error caused by the sensor noise in PES. For the reference correction design problem, a transition matrix which can describe the error propagation characteristics of SSTW is derived and utilized for reference correction for the next servowriting. Simulations results verify the effectiveness of two suggestions.
