| Abstract: | To implement the two-photon multilayer data storage system, a confocal dual-pickup-head multilayer data storage system was set up by using high-precision focus servo and tracking servo technology of DVD, and the high-precision positioning of the R/W focus in the three-dimensional data storage material was implemented. To read and record in different layers, a 16bit-D/A was used to output the select-layer signal to control the Voice Coil Motor (VCM) and move the focus between different layers. In this paper, the storage system was illustrated and the mathematical model was built. Both experiment and simulation results show the applicability of this technology. |
