dc.description.abstract | In this paper, we present a new tracking control method for holographic digital data storage systems. Holographic data storage systems that use disk media need a different tracking method from those that use optical and hard disk drives. Here, we present the design and implementation of the controller. Due to the intermittent characteristics of the tracking error signal (TES), the tracking controller is designed to regulate the tracking error only while valid TES is generated. Since the valid TES appears intermittently, we use a feedforward controller while the TES is not valid. Furthermore, the feedback control and the feedforward control are mode-switched depending on the RF sum signal level. We also show the stability of the closed-loop system employing the mode-switching controller. Experimental results show the effectiveness of the proposed tracking control algorithm. For a +/-100 mu m repeatable run out at 1 Hz, we were able to reduce the TES to 3.13 mu m (1 sigma) with mode-switching control. | - |
