Beating the back-up blues

parts are static," says Dr Chris Marrows, reader in condensed matter physics at the University of Leeds.

Compared with flash memory - the kind of solid state memory you find in flash drives and iPods - racetrack memory's huge advantage is on price. It is estimated that a racetrack memory in a computer would be 100 times cheaper per bit than flash.

"Magnetic racetrack memory is designed to replace the hard disk, and it's estimated that it could compete on price since it's very dense it can store lots of bits of data on a small area of chip, as the information is stored in vertical towers," says Dr Marrows.

As well as being more reliable than hard disks, racetrack memory is also faster. There are no 'seek' times when the head has to search the disk for information, so computers would be able to boot up almost instantly.

The next stage for the team is to develop better materials from which to make the racetrack components. A fully working race track memory is anticipated to be available within 10 years.
