Problems solved by technology

[0005] However, the laser five-dimensional storage technology uses nano-gold as the data recording point. Nano-gold is expensive. If the service life of the storage medium is not long, its application prospects are not optimistic. The development of long-life data storage discs is the promotion of this technology. Base
The preparation of pure inorganic material discs is the development direction of long-life discs, such as ceramic or glass discs, but ceramics or glass often require high temperature sintering, and gold nanorods cannot withstand such high temperatures, and traditional processes cannot be borrowed

Abstract

The invention belongs to the optical information storage technical field and discloses a high-capacity long-service life novel optical disk and a preparation method thereof. The high-capacity long-service life novel optical disk is characterized in that: the surface of a glass substrate is covered with a hybrid material film layer; and high-density gold nanorods are dispersed in the hybrid material. The chemical properties and thermodynamic properties of a data storage optical disk prepared by the method are stable, and long-time storage of recorded data can be realized.

Description

technical field [0001] The invention relates to a data storage optical disc with ultra-long lifespan composed of a hybrid material and a metal material, in particular to a data storage in which a noble metal nanostructure is directly dispersed in a composite material formed by hybridization of an inorganic material and an organic material The optical disc and its preparation method, as well as its application in high-density optical storage, belong to the technical field of optical information storage. Background technique [0002] With the popularization of computer technology and the rapid development of the Internet, all kinds of information are increasing explosively, and people's daily life also largely depends on information. After digitization of information, data storage with higher storage density, larger storage capacity, faster access speed, longer life, and lower cost is required. For storage technology, the most critical thing is the storage medium and the way ...
