Abstract

The invention provides a method and device for reading and writing optical disc information based on nano-lithography, wherein the writing method includes: adopting nano-lithography method to write ultra-high-density optical disc storage information; adopting fluorescence method to store information; utilizing two-photon absorption characteristics to realize Write and store multi-layer optical disc information. The reading method includes: super-resolution digital information reading method to read optical disc information; adopting "confocal tomography" reading method can realize multi-layer storage information reading of optical disc. The invention is beneficial to reduce the size and spacing of information recording points, realize stable and long-term storage of ultra-high-density information on optical discs, and effectively and high-speed extraction of information stored on ultra-high-density optical discs.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a method and device for reading and writing optical disc information based on nano-lithography. Background technique [0002] With the development of technologies such as gene sequencing and brain activity reading, not only a large amount of data is generated, but also higher requirements are put forward for how to store the data effectively, stably and accurately. Based on the above-mentioned background, the optical disk storage technology has well adapted to the requirements of the times due to its advantages of energy saving, long storage life, good safety and easy processing. As for optical disc technology, the limitation of storage capacity seriously hinders the development of optical disc technology. [0003] In order to increase the capacity of the optical disc, the traditional technical route is to reduce the size of the recording spot. With the successful development ...
