Hitachi, Japan, and Kyoto University’s School of Engineering have teamed up to develop a quartz glass memory chip that can hold information for at least hundreds of millions of years.
Hitachi says that new materials can withstand extreme temperatures and harsh environmental conditions and can be stored almost permanently; the company says that the stored data can be read with ordinary optical microscopes.
For those who transcribe vinyl records for CD storage, and later have to put CD music on MP3s, this technology that never needs to change storage devices is very attractive.
Hitachi Research Institute staff Kazui Hiroyuki said: "Humans create explosive data every day, but from the perspective of saving materials for future generations, we have not improved since the era of stone engraving."
He also said: "The possibility of losing information is increasing." Current CDs and hard disks, etc., have only a few decades of life, the longest century.
The new technology stores data in binary form, and uses lasers to record data on quartz glass wafers to record data. The storage device made of quartz glass has a length and width of 2 cm and a thickness of only 2 mm, while quartz glass has a high degree of stability and good toughness.
