Research background- Trends in storage technology
The need to store the amount of data: 2009 0.8ZB, 2020 will reach 35ZB; 90% for cold data (i.e. annual visits in 3 to 5 times, but very important data), the main storage medium for the disk and tape, storage security can only be 5~10 years; In the era of big data, need to develop a new storage technology of safety, energy saving, long life and high storage density.
research significance
Ultra high density optical storage materials and technology belongs to the "Pearl River Delta region reform and development plan (2008-2020)" and "developmen of Guangdong province science and technology " The 12th Five-Year "plan" put forward in the development of new materials (special functional materials and optical information storage materials)
