IBM drives tape density further
IBM scientists have demonstrated an areal recording density of 123-billion bits of uncompressed data per square inch on low cost, particulate magnetic tape – a breakthrough which represents the equivalent of a 220Tb tape cartridge that could fit in the palm of your hand. To put this into perspective, 220Tb of data is comparable to 1,37-trillion mobile text messages or the text of 220-million books, which would require a 2 200km bookshelf spanning from Las Vegas to Houston, Texas.
