A new method of calculation prevents location data from being exposed.
Digitalisation means more and more data is being generated. Now, an international research team from England and Australia has developed a new magnetic molecule to improve storage capacity.
The team sandwiched the rare earth element dysprosium between two nitrogen atoms. A hard drive made up of such molecules could save around 3 terabytes per square centimetre – equivalent to 500,000 thirty-second-long videos.
The high density is achieved by storing information directly in the molecules rather than by magnetising multiple tiny regions. The operational temperature currently stands at -173°. Large data centres could potentially cope – perhaps with the help of laser light?
Artificial DNA might be another promising storage option.
