To put this into perspective, 220 terabytes of data is comparable to 1.37 trillion mobile text messages or the text of 220 million books, which would require a 2,200 km (1,400 miles) bookshelf spanning from Las Vegas to Houston, TX. LAS VEGAS - 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 220 terabyte tape cartridge that could fit in the palm of your hand.
