A high capacity storage device from Sony


Technically explained, Sony optimized a commonly-used process called “sputter deposition,” which creates the particles to keep them from growing too big as well as making their magnetic properties more uniform. The process involves ions onto a layer of polymer film substrate. Sony’s magnetic layer of fine particles has an average size of 7.7 nanometres, In other words, the 185TB tape is about 74 times the capacity of current tapes or 3,700 times more storage than a Blu-ray disc. This is also five times the 35TB capacity of the cassette developed by FujiFilm and IBM in 2010.  Such tapes are used for most high-capacity data archiving, so this is a tape for businesses. One such cassette could store all the messages  from Twitter at this time. The producer hopes increase recording densities even further.
