Near field optical storage has the advantages of high density and large capacity and can take advantage of many existing related technologies. It is estimated that near-field optical storage density can reach 7 Gbit / cm2. It can also use air suspension head technology in hard disk drives and magneto-optical storage Technology, etc., to make research and development of near-field storage more rapid. At present, there are mainly three kinds of schemes for near-field optical storage: the probe type scheme, the super-resolution near-field structure and the solid immersion lens scheme. All three schemes realize the high-density storage by reducing the recording spot by different methods. The principle, research status and materials of near-field optical storage are introduced. The implementation methods and development of three kinds of near-field storage solutions are described in detail. The advantages and disadvantages of these three schemes are analyzed
