The amount of data you can squeeze onto a hard drive continues to grow by leaps and bounds, with Seagate announcing a 60TB SSD late last year. But thanks to IBM and Sony, tape might still reign supreme when you need to archive massive amounts of data, as the companies have jointly developed a new kind of tape that can reportedly hold 201-gigabits, or roughly 25GB, per square inch.
IBM’s researchers developed a new read head just 48-nanometers in size that was capable of accurately reading the minuscule magnetic particles on Sony’s new tape, as well as new servo technology allowing for precise control of the tape as it flows through the machine. Accuracy and precision have to be improved as the magnetic particles holding the data get smaller and smaller.
