British scientists have come up with an optical recording with a density 10 thousand times higher than on Blu-ray discs

Researchers from the University of Southampton (UK) came up with a method for high-density data recording using glass lasers, which they called five-dimensional (5D). In the course of experiments, they recorded 1 GB of data on a square glass of 2 inch6, which in the future can give 500 TB on a Blu-ray disc. But the problem remains the low write speed of 225 KB / s - it took 6 hours to write the test data. Image Source: Yuhao Lei and Peter G. Kazansky, University of Southampton
