Paper Abstract
In order to read out correct data from a disk-type holographic storage system, it is very important to implement a servo control in pickup modules, like as in conventional CD-ROM and DVD-ROM. We propose a novel servo-control method by use of a glass-plate on optical axis, which is able to compensate readout errors mainly coming from mechanical wobbling of the holographic disk. By rotating the glass-plate within ± 10 degrees, we can reduce the readout position-errors of ± 200 μm to ± 15 μm.
