Problems solved by technology

[0004] Super-resolution optical storage technology can effectively increase the recording density, because the photoinhibition effect of the peripheral hollow vortex light can effectively reduce the photo-induced effect of the central Gaussian light on the material, thereby increasing the resolution of the recording point. At present, the super-resolution optical storage technology Although the research has made some progress, further research is still needed for super-resolution optical storage materials. The photostability and thermal stability of existing super-resolution optical storage materials need to be further improved, and the half-life time at room temperature is relatively short.

Description

technical field [0001] The invention relates to the technical field of optical storage materials, in particular to super-resolution optical storage materials. Background technique [0002] Optical disc storage technology uses lasers to write and read information on the medium. This storage medium was originally non-magnetic, and later developed into a magnetic medium. The information written on the CD cannot be erased and is an irreversible storage medium. When using magnetic media for optical storage and recording, the original written information can be erased, and new information can be written, which can be erasable and rewritable for repeated use. [0003] With the continuous development of high-tech, especially the needs of high-tech industries such as information technology, new optical storage technology has also emerged as the times require. In the field of optical storage, the main features are strong repeatability, high storage density, fast response speed, and...
