IBM Research establishes new record in magnetic tape data density |
|
|
IBM researchers demonstrated the world record in areal data density on linear magnetic tape, which is sure to be a significant update to one of the computer industry's most resilient, reliable and affordable data storage technologies. The breakthrough beefs up tape technology at an increased capacity for years to come, with important implications since tape storage systems are more energy efficient and cost-effective than hard disk drive storage systems. With the physical world becoming increasingly networked with sensors, huge volumes of data are generated in various formats, ranging from medical images to security camera feeds to supply chain sensors to financial records, which needs to be archived, replicated, and/or retained or regulatory compliance. The scientists at IBM Research – Zurich, in cooperation with the FUJIFILM Corporation of Japan, recorded data onto an advanced prototype tape, at a density of 29.5 billion bits per square inch – about 39 times the areal data density of today's most popular industry-standard magnetic tape product. "This exciting achievement shows that tape storage is alive and strong and will continue to provide users reliable data protection, while maintaining a cost advantage over other storage technologies, including hard disk drives and flash," said Cindy Grossman, vice president, IBM Tape and Archive Storage Systems. These new technologies are estimated to enable cartridge capacities that could hold up to 35 trillion bytes (terabytes) of uncompressed data, about 44 times the capacity of today's IBM LTO Generation 4 cartridge. A capacity of 35 terabytes of data is sufficient to store the text of 35 million books, which would otherwise require 248 miles (399 km) of bookshelves. IBM has a long history of magnetic-tape data storage. Its first commercial tape product, the 726 Magnetic Tape Unit, was announced nearly 60 years ago. It used reels of half-inch-wide tape that each had a capacity of about 2 megabytes. The areal density demonstration announced today represents a potential increase in capacity of 17,500,000 times compared with IBM's first tape drive product. |
