Future tape 220 terabytes on one reel

Researchers recorded 123,000,000,000 uncompressed data bits per square inch tape cheap. The entire cartridge placed 220 terabytes of information. So scientists have exceeded 88 times the existing since 2012 standard LTO-6, which provided 2, 5 TB of data on a product of the middle class.





This device, according to scientists from IBM, is capable of recording data on a magnetic tape with an efficiency of 123 billion bits per square inch. The scientists used a tape diameter of 10 inches and a width of 2 cm.



"The tape is indeed growing," - says Mark Lantz, Director of Research IBM Research in Zurich, Switzerland. While the consumer and SMB markets, the demand for tapes falls due to lower prices for hard drives, archival technologies "revive" this storage device. Another factor in the revival of the tape - slowing growth in the hard disk, which is difficult to keep up with Moore's Law, said Lantz.

IBM has not yet announcing the finished product, but sees its future in cloud storage systems. According to Lanza, several companies offer cloud solutions using magnetic tape. The advantage of the technology - the price: each gigabyte costs 2 to 3 cents. A minus - in time because of a few tens of seconds to a minute is required to access the files. The technology is suitable for those data, the work that does not require high speed. In particular, about 80% of corporate data can be written to tape.
