Abstract

The present invention relates to a sapphire information storage optical disc, which comprises a sapphire substrate. The surface of the sapphire substrate is provided with a recording track. A plurality of information pits are formed on the recording track. The sapphire substrate record and stores the data information through the information pits. By utilizing the sapphire substrate, the information storage is realized through the laser marking of information pits, so that the information can be stored for a long period of time.

Description

technical field [0001] The invention relates to the field of optical discs, in particular to a sapphire information storage optical disc and a manufacturing method thereof. Background technique [0002] Optical discs still have an advantage in the field of archival data storage. For example, when precious documents such as important documents, historical archives, world cultural heritage information, and genetic data need to be stored, optical disc storage is often the preferred solution. [0003] Since the time limit for storing the above-mentioned data information is relatively long, higher requirements are placed on the reliability and timeliness of the data stored on the optical disc. Most of the commonly used optical discs are based on polycarbonate (PC) materials. Due to the low stability of the PC material itself and the weak adhesion between the metal layer and the base layer of the optical disc, it is difficult for the current optical discs to meet the requirements ...
