Study of the Signal Readout System in a Multilayered Waveguide Memory

Signal readout technique is very important for the multilayered waveguide optical memory, which is based on an optical waveguide principle and a promising subject in the optical storage field compared to other 3D optical memory techniques. In this paper, the electric system is designed, the controlling system design ,the servo system design and the pre-signal design are discussed in detail, the key steps of testing multilayer disc are given in this paper, the experiment shows that the multilayered disc system works well.
