German startup Cerabyte has developed an inexpensive, highly reliable device for storing information with an almost unlimited service life. It is a storage device in the form of a square glass plate on which a nanoceramic layer is applied.

Data is written on the cartridge in the form of QR code-like patterns using a femtosecond laser pulse. It creates holes or leaves gaps in the ceramic layer as binary code (0 and 1).

As you move forward a series of characters are recorded and as you move backward these are read and checked by the microscope camera. The data collection process is similar except that a microscope camera is used to read the content.

Cerabyte claims that data stored in this way is not afraid of temperature changes from minus 273 to plus 300 degrees Celsius, aggressive or acidic environments, radiation and electromagnetic effects, in general, the device should save data even if a nuclear explosion occurs.
