An optical storage method and system for introducing fluorescent signals into an anisotropic structure

Abstract

The invention discloses an optical storage method and system for introducing fluorescent signals into an anisotropic structure, belonging to the field of optical storage, including: taking the data to be stored as target data, determining the corresponding delay value L and the direction of the optical axis D and fluorescence signal intensity I, and determine the position P of the anisotropic structure in the processing material according to the storage address of the target data; after setting the intensity and polarization state of the first laser according to the retardation value L and the optical axis direction D, use the first The laser writes the anisotropic structure at the position P in the processed material; during the process of writing the anisotropic structure, the fluorescence signal intensity I generated by the excitation of the material defect introduced by the first laser is determined ini , and according to the fluorescence signal intensities I and I ini After setting the intensity and action time of the second laser, the second laser is applied to the position P in the processing material to adjust the intensity of the fluorescent signal to I by utilizing the thermal effect of the second laser. The invention can increase the capacity of optical storage.

Description

technical field

[0001] The invention belongs to the field of optical storage, and more specifically relates to an optical storage method and system for introducing fluorescent signals into an anisotropic structure. Background technique

[0002] In recent years, with the rapid development of information technologies such as the Internet and the Internet of Things, the amount of data generated by humans in production and life has also exploded. For enterprises, data centers and other institutions, how to effectively save these massive data is an important challenge. The current mainstream storage technologies often have certain disadvantages when faced with new demands. For example, hard disks such as common HDD (Hard Disk Drive, hard disk drive), SSD (Solid State Drive, solid state drive) need to consume a lot of power during use, and the service life of these devices is not long, and need to be replaced every 3 to 5 years. Data is transcribed and not suitable for long-term...
