Since the end of the 20th century, with the exponential growth of data storage needs, scientists and engineers have been looking for more durable and stable data preservation media. Among them, quartz glass, as a non-traditional but extremely durable storage material, has gradually attracted the attention of global scientific research teams, and has made major breakthroughs in recent years.
1. The data storage of Japanese quartz glass is over 100 million years
As early as September 2012, Hitachi Manufacturing Co., Ltd. of Japan, in collaboration with researchers from Kyoto University, announced the successful development of quartz glass data storage technology, which marked a new era in the field of data storage. By taking advantage of the stable chemistry of quartz glass and the unique way in which it can carry information in its microstructure, this technology achieves the goal of securely storing data for 300 million years, significantly exceeding the lifespan of traditional storage media such as optical discs.
2. The data of Microsoft quartz glass in the United States is broken TB
After several years of development, in November 2019, Microsoft USA further presented the results of its project called "Project Silica", which also focused on the possibility of quartz glass as a long-term storage medium. Using high-density laser etching, the researchers encoded the iconic 1978 film "Superman" onto a quartz glass slide just 2 millimeters thick, claiming that such a form of storage would ensure that the data would not be compromised for 1,000 years or more. Not only that, but Microsoft also revealed a more advanced development, that is, a palm-sized piece of glass can theoretically store up to 7TB of data, which provides an unprecedented solution for archival storage and long-term protection of historical data.

3. Chinese enterprises practice quartz glass data storage - the launch of quartz discs
With the passage of time and technological iteration, Chinese companies have also made significant progress in this field, directly exhibiting quartz glass storage data products with commercial potential - quartz CD-ROMs.

These products not only inherit the in-depth research on the superior characteristics of quartz glass, but also optimize the design at the practical application level, so that the security, capacity and reading efficiency of data storage have been improved, and meet the growing demand for massive data storage market.

To sum up, from the pioneering research in Japan, to Microsoft's technological innovation and verification, to the productization of Chinese enterprises, quartz glass data storage technology has experienced a leap from laboratory concept to commercial application on a global scale, and has become an important tool to meet the challenges of the era of big data. Regardless of the 300 million years claimed by Japan, the thousands of years claimed by Microsoft, and the 1 million years claimed by Chinese companies, they are far beyond the existing mechanical hard disk or solid-state storage years, this cross-era storage technology not only provides the possibility for the long-term record of human civilization, but also opens up a new path for the development of information technology in the future.
