Sony and IBM collaborate to develop 330TB tape storage

Sony and IBM have collaborated on a new Magnetic Tape Storage Technology. In a press release yesterday Sony announced the development of tape storage with the industry’s highest areal recording density of 201Gb per square inch. In comparison with tapes available on the market at this present time the new tapes will offer approx 20x greater capacity. That is indeed a significant advancement. What it means in practice is that backup tape cartridges, currently topping out at 15TB storage, will be available in capacities up to 330TB following commercialisation.

Magnetic storage tapes are often used in large scale backup operations. As most will be aware, people, companies, and the cloud are squirreling away increasing amounts of data at an alarming rate and backups are important in the event of inevitable hardware failures.

So, how have Sony and IBM managed such a ground breaking boost in tape recording capacity? They have simultaneously leveraged a number of complementary technologies:

Looking at the data density on offer in the prototype tapes, one of these 330TB tapes has a volume of about 0.33 litres, that’s similar in volume to a standard soft drink can. Currently magnetic storage on spinning disks is much less space efficient with a 3.5-inch HDD (also about a third of a litre volume) which top out at 12TB.

Sony says it is working on the commercialisation of this next-generation magnetic tape storage technology.
