Abstract: Though optical data storage technology has attractive potential because of its long storage lifetime and low energy consumption, current optical data storage technologies are challenged by their capacity and dentistry for big data application. Dual-beam super-resolution optical data storage technology exhibits obvious advantage in ultra-high capacity and density due to the overcoming of optical diffraction limit. This work illuminates the key problems in the industrialization of dual-beam super-resolution optical data storage technology, and discusses some basic solutions to these obstacles.
