A method for performance assessment of a variable-gain control design for optical storage drives is proposed based on a quantitative performance measure. The variable-gain strategy is used to overcome well-known control design tradeoffs (for linear systems) between low-frequency tracking properties and high-frequency noise sensitivity. A performance analysis is conducted to support the design of the variable-gain controller which subsequently is shown to outperform linear controllers
