Abstract
The high precision tracking servo control would play an important role in the next generation near-field optical data storage systems where the desired tracking error should be below 5 nm under various unknown situations. It is proposed in this paper to use an adaptive regulation approach to maintain the tracking error below its desired value, despite unknown track eccentricity and external force disturbance. The experimental evaluation result show the effectiveness of the proposed control approach.
