Sony's new magnetic tape technology enables 185 TB cartridges

One of the joys of old science fiction movies is watching the giant reel-to-reel tape drives spin around as they serve computers less powerful than a modern wristwatch. But magnetic tape isn't just something found in old UFO episodes; it’s a key component in modern digital systems required to keep modern online systems reliable. At the INTERMAG Europe 2014 international magnetics conference in Dresden, Sony announced a new breakthrough in magnetic tape technology that keeps the medium relevant by allowing a tape cartridge to carry 74 times the data of a conventional data tape, or the equivalent of 3,700 Blu-ray discs.

In 2014, Sony made a cassette tape that can store 185TB of data
