Смысл: The text explores the evolution of optical storage, highlighting a new 200 TB disc from China, while questioning if these high-capacity innovations will ever become commercially viable or remain laboratory curiosities.
Chinese researchers created a 200 TB optical disc for archival storage, though mass production is hindered by expensive and bulky writing hardware.
Смысл: The text reports on a scientific breakthrough where researchers used a specific form of titanium oxide to create optical disks with theoretical capacities up to 1,000 times that of Blu-ray (up to 25 TB), while significantly reducing production costs.
University of Tokyo chemists discovered that using titanium oxide can create optical disks with capacities up to 25 TB at a much lower cost than current Blu-ray materials.
Смысл: The main idea is the presentation of a theoretical high-density optical storage technology created by students, balancing their ambitious scientific goals with the practical skepticism of the technical community.
Students from Nizhny Novgorod developed 'Digital Sandwich,' a theoretical laser-based storage device capable of holding 28TB on an A4 sheet using nanostructures in organic glass.
