THROW AWAY YOUR HIGH capacity flash drives! Tape is king once more! Continuing the renaissance of a format that dates back to 1952, the same year as Alan Turing's seminal paper The Chemical Basis of Morphogenesis, researchers at IBM labs have created a tape storage system capable of an aerial recording density of 123 billion bits of uncompressed data per square inch.
That's equivalent to a palm-sized 220TB cartridge. Or about 1.37 trillion text messages.
The speed at which tape can be recalled means that the format is best served for cold storage (write once, read many), but it will give some of the newer kids on the block, such as SanDisk's 512TB InfiniFlash array, something to think about because of its potential cost-effectiveness.
IBM states that a single cartridge is the equivalent of a bookshelf stretching from Las Vegas to Houston (2,200km).
“With this demonstration, we prove again that tape will continue to play an important role in the storage hierarchy for years to come,” added Evangelos Eleftheriou, IBM Fellow. “This milestone reaffirms IBM's continued commitment and leadership in magnetic tape technology.”
The continued development of the tape format is nothing new. This is the fourth time since 2006 that IBM has teamed up with Fuji and cracked the record.
Last year, Sony managed to cram 148GB per inch on to a tape format developed in association with IBM, only for the IBM/Fuji alliance to knock it out of the park weeks later clocking 154GB per inch.
IBM scientists are exploring ways of combining this technology into services such as Openstack Swift, making for a very low cost big data platform.
The team has been working on perfecting a technique with a combination of higher track densities, thanks to head alignment accurate to 6nm, a more accurate write head, writing to much finer barium ferrite particles and more accurate signal processing algorithms based on noise-predictive detection principles.
So a little bit more advanced than your C90 mixtape then. µ
