What new data storage world record has IBM set?

Answer: storing more than 200 gigabits per square inch on magnetic tape

IBM researchers have nailed down how to pack as many as 201 gigabits of information on a square inch of magnetic tape. On Aug. 2, the company revealed that it had created a new storage solution that holds 330 TB of uncompressed data on a palm-sized cartridge. While magnetic tape is far from revolutionary in the tech world, the density of data is unprecedented — and has cemented the company its fifth world record. For reference, 330 TB of data equates to around 330 million books.

The advance is significant in the sense that magnetic tape is currently the most cost-effective and efficient way to store, back up and archive vast amounts of data. To achieve the feat, researchers developed signal-processing algorithms, advanced servo controls for more accurate tape head positioning and low-friction tape heads that allow for smoother operation.
