Abstract

In conventional angle-multiplexed holographic data storage, data pages are recorded and are retrieved with stop-go rotation. In this paper, we propose an effective servo method based on the disturbance analysis of holographic disc drives. Our experimental results indicate that the eccentricity and deviation of the disc provide sufficient information in the disturbance estimations to stabilize the servo system. The results also show that the vibration due to stop-go rotation can be ignored.
