MADE IN IBM LABS: IBM researchers achieve record density on magnetic tape, Zurich, Vienna, January 22, 2010: researchers from IBM Zurich Research (NYSE: IBM) 29.5 gigabits per square inch (around 6.45 cm2) on an advanced test tapes have written in cooperation with the Japanese company FUJIFILM that corresponds to the 39-fachen density of the currently leading industry standard magnetic tape product. 1 this milestone shows that one of the oldest technologies for data storage has the potential, to provide further capacity increases for many years. Today’s announcement signals to customers that the tape storage technology can maintain its cost advantage over hard drive save and Flash and allows future affordable and robust data backup\”, says Cindy Grossman, Vice President, IBM tape storage and archiving systems. Companies use magnetic tape typically large amounts of important data to secure, not regularly used or no access in the Require millisecond range. These include data and video archive, backup files and backup copies in the context of disaster management or regulatory compliance. To achieve the demonstrated record storage density, researchers developed the IBM several new data-recording technology.
In addition she worked during three years intensively with FUJIFILM on the optimization of the next generation of double coated, barium ferrite particles-based magnetic tape. A tape cartridge in the size of one in the industry-standard LTO (linear tape open) specified cartridge up to 35 terabytes could uncompressed data aufnehmen2 with the newly developed technologies and bands. This corresponds to about the 44 fachen3 of the capacity of today’s LTO cartridges of the fourth generation, which have about half the size a VHS video cassette. To illustrate: 35 terabytes correspond to the amount of text in about 35 million books on data. To keep them on, one would need a bookshelf in a length of about 400 kilometres. This demonstration is an important step on the way to the development of tape storage with an areal density of 100 billion bits per square inch.
