Fujifilm has presented that it has put a new world yarn by constructing a magnetic storage tape that can retailer a staggering 580 terabytes of files.
The leap forward, developed jointly with IBM Evaluate, uses a new magnetic particle known as Strontium Ferrite (SrFe), normally historical as a uncooked material for making motor magnets. Fujifilm has been investigating Strontium Ferrite as a conceivable successor to Barium Ferrite (BaFe), which is the main material this day.
SrFe has been chanced on to dangle greater magnetic traits and 60% much less particle quantity than BaFe. And cherish BaFe, SrFe is a chemically real oxide, which manner it would composed make successfully for lengthy-term data preservation.
“SrFe is a magnetic material that has very high magnetic properties and is real to preserve high efficiency even when processed into aesthetic particles,” Fujifilm says. “Magnetic tapes historical on this test had been produced at the firm’s present coating facility, confirming the flexibility to make stronger mass manufacturing and commercialization.”
Recordsdata on the tape is saved at a yarn-breaking density of 317 gigabytes per square proceed thanks to new technologies developed by IBM, along side a new low friction tape head technology and the actuators and servos in the encourage of it. The pinnacle’s stir and accuracy are great.
“Like minded let me geek out for a 2nd,” writes IBM overview manager Ticket Lantz. “When tape is being learn it’s miles streamed over the top at a stir of about 15 km/h and with our new servo technologies we’re composed able to region the tape head with an accuracy that is about 1.5 cases the width of a DNA molecule.”
The ensuing data storage potential of the new tapes is roughly 50 cases greater than the most modern cartridges on the market this day.
To place 580 terabytes in standpoint, it’s roughly the identical of 120,000 DVDs or 786,977 CDs — IBM notes that stacking that many CDs would consequence in a tower 3,097 feet (944m) sizable, or taller than Burj Kalifa, the world’s tallest building.
All that data can now match in a tape cartridge in the palm of your hand.
“When it comes to costs, storing data on tape is pennies per gigabyte and when now not in exercise, tape requires no energy unlike irritating disks and flash,” IBM writes. “Put aside merely, tape-saved data ensures that cloud suppliers can dangle the data they need as soon as they need it.
“As successfully as, when saved successfully, data recorded on tape this day will composed be readable in 30 years.”
