Research on the Characteristic of the Model of Self-servowriting in Hard Disk
硬盘自伺服刻写模型特性研究

Self-servowriting is a good method which deals with servo information writing.This paper analyzed the chara-cteristic of servo model.It shows that position precision is the most important criterion to the validity of self-servowriting.In the paper three different controllers were designed to centrol the self-servowriting process.The experiment data shows the importance of position precision in self-servowriting.This paper indicated the robust controller can resist outer disturbance and provide the position ...
