The glass: new way to keep information

quartz crystal

The Japanish company Hitachi presented a prototype of a digital storage of information consisting of small pieces of quartz crystal able for keeps information for millions of years.

The life of a CD or a hard drive is limited to several decades so that researchers are perfecting a glass to archive forever. Hitachi proposes keeping binary information into four layer of dots printed ina small quartz glass plate. Glass resists to water, heat, radiation and the most of chemicals. storing binary data into four layers of dots printed in a small quartz glass plate, a material resistant to water, heat, radiation and most chemicals. In each layer holds about 40 Mb but memory can be enlarge by increasing the thickness.

 

 

Definety the Japanish science advance a lot, Before, they get to keep a lot of information in a little memory card, and there you can put films, music, pictures, programmes, documents... But now, we can keep information in a small peace of transparent glass! It's a very interesting discovery for the world because we can keep better our information and we can read it with a optical microscope.
