Scientists develop optical drive with one petabit storage capacity – image and sound – .Geeks

Scientists have managed to store more than one petabyte of data on an optical drive. They have developed a new material that acts as a carrier and uses a dual laser setup that can make indentations up to 54 nanometers wide.

The new photosensitive material is called AIE-DDPR and can have hundreds of layers. Scientists have It said The material took ten years to develop, but the substrate will be suitable for storing large amounts of data. Each layer within the substrate will be barely one micrometer thick.

The data is etched onto the AIE-DDPR layer using two lasers. By using the two different lasers side by side, the scientists were able to create microscopic gaps up to 54 nanometers wide. These slots are necessary to store binary codes on the substrate that can be read again later. According to scientists, this reading is done again using two tandem lasers.

Scientists write In their research paper These optical carriers can be useful in large data centers. They are currently trying to improve writing speed and associated power consumption. The process of producing this optical disc would be similar to that of producing a DVD, which is why scientists are also considering commercial applications. An optical disc containing an AIE-DDPR substrate can currently roll off the production line in about six minutes. More or fewer optical layers may also be added to the disk, resulting in different storage capacity. A petabit equals about 125,000 gigabytes.
