Paper Abstract

The ultra-high speed processing and large storage capacity are the requirement of information technology. The multi-layer CD storage technology is used to enlarge the storage capability. In order to avoid some problem such as the crosstalk in different layer and the tracking of arbitrary layer, the dip-incidence and dip-reflection device is proposed in the focus system of wave-guide multi-layer CD. The improved astigmatism method is applied in focus system for better linearity. It can be proved by the simulation and experiment that the light intensity reflected from each layer is strong enough to receive; Moreover, only one layer's photospherical facula is leaved on the receiver for a size-limited receiver. It is identical with simulation result and sampled image signal in experiments. It can be proved by the focusing results of simulation and experiment that the signal of each layer is received and separated by the receiver.
