Introduction As track density in tape recording systems increases, the need for high performance control becomes crucial due to significant high frequency disturbances such as lateral tape motion, inner track variability, servo track variability, noise and input saturation of the servo actuator. An essential step in designing high performance model based controllers is the identification of low order, control-oriented models. The objective is to identify not only the plant, but also the sensitivity function which is a measure of the closed-loop disturbance rejection.
