Cassette tapes are the future of big data storage
THE cassette tape is about to make a comeback, in a big way. From the updates posted by Facebook’s 1 billion users to the medical images shared by healthcare organisations worldwide and the rise of high-definition video streaming, the need for something to store huge tranches of data is greater than ever. And while hard drives have traditionally been the workhorse of large storage operations, a new wave of ultra-dense tape drives that pack in information at much higher densities, while using less energy, is set to replace them.
Researchers at Fuji Film in Japan and IBM in Zurich, Switzerland, have already built prototypes that can store 35 terabytes of data - or about 35 million books’ worth of information - on a cartridge that measures just 10 centimetres by 10 cm by 2 cm. This is achieved using magnetic tape coated in particles of barium ferrite.
