Optical discs can reliably preserve massive data for long-term in low-cost. When querying these accumulative data, it is necessary to quickly obtain the query results, and to seek the physical location of the corresponding optical disc. To this end, it demands each disc have a unique identifier in both the cyber and physical worlds, make massive data be managed effectively, conveniently, and credibly. This paper designs a batch-disc automatic identification system, which integrates common optical disc recorders, printers, and cameras, automatically to print physical label and to burn logical identification on each disc. Consider that each commodity component has its own internal independent timing control and a specific external interface. This study designed and developed a customized mechanical structure, as well as a global software scheduling mechanism to coordinate physical behavior and logical control. The experimental results show that the system can continuously identify 200 discs at once, averaging 2 minutes per disc.
