For the first time successfully manufacturing optical CD discs up to 700TB

Scientists from Shanghai University of Science and Technology, RMIT University and National University of Singapore NUS worked together to research on improving the storage density of optical drives . They succeeded in 'stuffing' 700TB of data which is equivalent to 28,000 25GB Blue-ray discs and all of them are burned into the only 12cm CD we used to use.

This study of scientists was conducted with the aim of finding an efficient way to store data, leading to a reduction in the carbon footprint of data storage centers, and at the same time they wanted to reduce the dependence on data. dependent on magnetic disks which have a more limited useful life.

If the shortcomings of optical CDs can be improved, it will bring a lot of benefits.

The study, published in the scientific journal Science Advances, argues that optical storage media use laser readers to operate, but the nature of this is limited by interference. reflect light, thereby reducing the storage capacity of optical discs. Therefore, instead of using traditional materials, scientists have used a new type of synthetic nanomaterials , combined with graphene oxide arrays , thereby creating UCNP-converted nanoparticles to increase data storage density to an unprecedented level.

If the shortcomings of optical CDs can be improved, it will bring a lot of benefits. The first is that the technology that uses lasers to read data is quite inexpensive, thereby reducing the operating costs of data storage centers. Not to mention the laser technology for reading this new type of CD can use less expensive technology than traditional optical read and write technologies that are expensive and cumbersome to operate.

The researchers of this project assert that this new optical disc technology holds great potential, they help to optimize and open a new path to solve the global challenges of data storage today. in.
