摘要：

Based CD/DVD servo technology and two-photon absorption technology, a CD/DVD compatible three-dimensional optical storage system is built. Double bald synchronization performance is tested using the direct method and indirect test method, test results show that under certain conditions, double bald synchronization errors are less than 2 mu m, which basically meets the requirements of double bald three-dimensional optical storage system, however, the double bald synchronization error is still relatively large, in order to the laser beam is focused onto the information point at the strongest intensity, the reader module circuit of three-dimensional optical storage system needs to be improved, so that we can get smaller synchronization error and obtain the better storage results (C) 2015 Elsevier GmbH.
