Scientists at IBM have stored 330 terabytes of uncompressed data into a cartridge that fits in your palm, setting a new world record. The new record now stands at 201 gigabit per square inch stored on a prototype magnetic tape, which is over 20 times the areal density that current commercial tape drives use. For the uninitiated, areal density is the measure of information stored in a given area of surface. In comparison to this achievement, the first tape unit by IBM had used half inch wide tapes, which could store 2 megabytes of data. The new technology allows potential storage capabity of 201 billion bits per square inch on magnetic tape.
