Cerabyte demonstrated the functionality of an indestructible data storage system on ceramic-coated glass

Young German company Cerabyte showed created a working prototype of a data storage system on ceramic-coated glass and also demonstrated the process of recording information. Up to 100 PB can be recorded on each turntable with a side length of a few centimeters. This can be a more reliable and economical alternative to tape and optical libraries because glass and ceramics are not afraid of fire, water, radiation, magnetic fields and other influences.

The announcement of a glass recording system with a ceramic layer was made in September this year. Now the company has shown how this system works. At Video You can see how the glass plate is removed from the cartridge, placed on the recording and reading surface and how the recording process takes place.

The recording takes place in two passes. A femtosecond laser writes a line of information in one pass, and in a reverse pass a special camera reads the recordings and thus verifies the recording. When reading, the camera works in both directions, making this process twice as fast as recording.

The recorded data set is then stored in a cassette in a robot library and storage does not require energy. Records are recorded once and for all and do not require special procedures to maintain data integrity, such as those required for tape drives.

The ceramic layer on Cerabyte glass plates is between 50 and 100 atoms thick. Ceramic is applied to both surfaces of the plate. During recording, the laser burns holes in the layer and encodes the data in binary code (regardless of whether holes are present or not). The data recording format is ordinary QR codes, making the solution compatible with popular file systems and operating environments and programs. But each group of codes is so small that it cannot be seen by the normal eye.

Each laser-made hole in the ceramic is 100 nm wide. In the future, the developers promise a reduction to 3 nm, which will require something more complex than conventional cameras to read. For example, electron microscopy. Over time, this will not be a problem if Cerabyte’s idea finds support among industrialists. Currently, the company is only looking for people willing to implement its development.
