- Scientists have developed a kind of super DVD.
- Thanks to a special 3D storage process, almost 125,000 gigabytes of data fit on the disk.
- This makes the data carrier significantly superior to conventional hard drives.
Anyone who thought that CD, DVD or Blu-Ray had had their day was obviously wrong. Researchers are still working on small plastic discs and are currently making great progress in the field of data storage. Scientists at Shanghai University have figured out how to store up to a petabit of data (125,000 gigabytes / decimal) on a disc.
As Gizmodo reports, the information is stored in three dimensions. A new technology enables reading and writing on up to 100 data layers on an area of just 54 nanometers.
The amount of data is enormous and currently surpasses any conventional hard drive (HDD). These have now reached a capacity of around 24 terabytes, with SSDs it is a maximum of 30.72 terabytes – although several thousand euros are due here.
Of course, the comparison with CD, DVD and Blu-Ray is even more astonishing. The time-honored CD-ROM has a storage capacity of around 700 megabytes, DVDs around 4.7 gigabytes. Blu-Ray has already brought significant progress – there are blank discs with up to 100 gigabytes. In comparison to the “Super DVD”, this amount is also small.
The new storage disk is just 1.2 millimeters thick and offers space for around 25 million MP3s with an average size of 5 megabytes.
Big advantages over hard drives
If the new data storage comes, it could bring immense advantages for data centers, among other things. On the one hand, the space requirement would be massively reduced, and on the other hand, so would the energy requirement.
For the technique, the researchers also had to develop a new material called “Dye-Doped Photoresist with Aggregation Induced Emission Luminogens” or “AIE-DDPR” for short. This is a very uniform and transparent film that can be written on with lasers in the nano range.
It is not known when the new storage type will be ready for the market. It will also be interesting to see how the Super DVD will fare in terms of scratches.
