Researchers from Kyoto University in collaboration with Hitachi have announced that they have developed a quartz glass technology capable of successfully storing data for more than 300 million years. The material, highly resistant to heat and water, could be used to store cultural treasures and official documents of great historical importance for very long periods.
CDs, DVDs and other optical discs obtained by alternating layers of metal and resin are vulnerable to high temperatures and humidity and 'only' retain data for up to 100 years under optimal environmental conditions. The new technology uses laser beams to etch glass with digital binary data and an optical microscope to read it. One prototype, two centimeters wide and long and two millimeters thick, was able to store data at an information density 1,1 times that of a CD. The champion also passed a heat test brilliantly in which he was exposed to a temperature of XNUMX degrees Celsius for two hours.
