Made in Russia: a perpetual quartz mini-disk for storing information

Quartz mini disc

Well-known expression of Woland from the “Master and Margarita”: “Manuscripts do not burn”, alas, is not true. Fires, floods, dampness and just time are cruel not only to books, movies, sound recordings, but also to more modern media and storage media – cd-disks and their younger “brothers” flash cards.

As it turned out, their age is limited to just a few dozen years, and the mechanical strength of these “children” of modern technologies leaves much to be desired.

However, very soon new information carriers will appear in the Russian archives, which can be safely said: time for them is not powerful. Scientists of the Russian Chemical-Technological University have developed compact quartz disks with a capacity of about 1 Tb.

The protection and preservation of such a huge amount of information is reliably guaranteed by the recording technology – by layers, using a special laser, inside the carrier itself. Quartz disks are not afraid of fires and even powerful electromagnetic radiation. But most importantly, the employees of the archives will not have to rewrite information from them for at least a hundred years.
