When it comes to reading and writing data, tape cartridges are much slower than SSDs, and even hard drives. They鈥檙e mostly for data you don鈥檛 need day to day, but don鈥檛 want to say goodbye to. You鈥檒l also have to cough up close to ,000 for a tape cartridge reader, which is why the format makes far more sense for large corporations than individual users.Magnetic tape storage currently relies on the Linear Tape-Open, or LTO, format with LTO-8 being the highest capacity available today at 12 TB per cartridge鈥攐r 30 TB when that data is compressed which slows down the entire read/write process. LTO-9, expected to be available soon, will double storage capacities to 24 TB per cart, but earlier this year Fujifilm revealed a breakthrough that could push tape storage capacities to a staggering 480 TB in a decade鈥檚 time.AdvertisementAdvertisementTape Storage Could Soon Crush Hard Drives With 400TB CapacitiesIf you鈥檝e got a mountain of digital data to store but don鈥檛 necessarily need to access it every鈥?/p>Read moreData tape technologies also rely on a material called Barium Ferrite (BaFe) with microscopic magnetic particles that are aligned to encode data onto the long strips of tape, but we鈥檙e reaching the limitations of how far Barium Ferrite can be improved and optimized to increase storage capacities. As a result, Fujifilm has been researching a new material called Strontium Ferrite (SrFe) as an alternative because its particles are smaller than those in Barium Ferrite, allowing for increased density and, in turn, more data capacity. Tape cartridges packing 480 TB of data could be available by 2030, and unlike flash memory and hard drives, they can reliably store data for upwards of 30 years without the need for any additional power.Advertisement setTimeout(() => const adSlot = document.querySelector(.apscustom); const adFallback = document.querySelector(.ars-fallback); if (adSlot) if has been read, but theres no ad, then show the fallback if (adFallback && adSlot.offsetHeight single square inch of the material. At that density, a single tape cartridge could potentially hold up to 580 TB of uncompressed data. The breakthrough comes courtesy not only of the new magnetic coating, but also the development of new low friction tape heads that allow the tape material itself to be very smooth, improving the accuracy and reliability of what鈥檚 being read and written.Also playing an important part is IBM Research鈥檚 creation of new servo and controller technology. Those are the critical components that actually move and align the read/write heads so that the microscopic tracks of data on the thin strips of tape can be accurately read. IBM is now promising positional accuracy to within 3.2-nanometers so that as the tape whizzes past the heads at 15 kilometers per hour, they鈥檒l be positioned 鈥渨ith an accuracy that is about 1.5 times the width of a DNA molecule.鈥 As amazing as Fujifilm鈥檚 development of Strontium Ferrite is, the material is mostly useless in practical applications without the supporting hardware that IBM Research is now developing alongside it.Advertisement So when will 580 TB tape cartridges arrive? Given Fujifilm鈥檚 earlier breakthrough won鈥檛 be available as a consumer product for at least another decade, this new research is probably on an even longer timeline than that. It also remains to be seen if the use of Strontium Ferrite will continue the advantageous pricing of tape cartridges as a long-term storage medium, or if it will increase manufacturing costs and pricing. A decade is also a long time as far as technological evolution goes, so who knows how capacious hard drives will be once 2030 rolls around. At that point, tape cartridges might be looking for another big breakthrough to continue to remain a few steps ahead.

It took another four years to turn the prototypes into a product that could be put into mass production, and in 1971 Canon released the Pocketronic, based on the TI design, which weighed two-and-a-half pounds and eventually cost 0, or just shy of 0 in today鈥檚 money.AdvertisementAdvertisementTexas Instruments鈥 prototype handheld calculator pre-dated technologies like LED and LCD displays, instead using a thermal printer and scrolling tape to display numbers and values.Image: BonhamsBecause millions of them were produced and sold, if you鈥檙e a collector, finding a vintage Canon Pocketronic isn鈥檛 impossible.
