IBM researchers demonstrate magnetic tape storage density forty times B

With the newly developed technologies and tape cartridge in the future, an LTO format holds up to 35 terabytes of uncompressed data.

This corresponds approximately to the 44-times the capacity of today’s LTO tapes of the fourth generation. The researchers believe not, however, that the possibilities are exhausted with it. "This demonstration is an important step towards the development of tape storage with a recording density of 100 billion bits per square inch," said Evangelos Eleftheriou, head of the storage technology research at IBM Research in Zurich.

"The tape technology to their cost advantage over disk storage and flash can continue to maintain and continue to allow affordable and robust data protection," said Cindy Grossman, vice president for IBM’s tape storage and archiving systems. This is particularly true for the remaining uses of magnetic tape, such as securing large amounts of data that would not regularly required, such as data and video archives, backup files and backup copies as part of disaster management or legal compliance.

In terms of cost per gigabyte tapes are in long-term storage of data, IBM said in a fifth to one tenth of current hard disk storage. Another advantage is that unlike continually rotating disk tape cartridges require no power when not accessed.
