Such technologies are necessary to keep pace with the explosion of digital information”, says Evangelos Eleftheriou, IBM Fellow and Director of storage technology research at IBM Research Zurich. IBM is in a unique position to assist customers in the backup, storage, and analysis of rapidly growing volumes of data and to help them to improve their efficiency and profitability.” Because: long-term storage has become an absolute must for users at relatively low cost. Data are often in automated tape libraries tape recorded, in which a or some a few tape drives manage dozens to thousands of tapes. Tape libraries can now petabytes of data include representing millions of gigabytes. An examination of the cost per gigabyte shows that the costs for the long term storage of data on tape-based systems, Depending on their size, currently are one-fifth to one-tenth of today’s disk storage systems. In addition, tape cartridges cause no power consumption, as long as not they accessed, in contrast to the continuously rotating disks. This offers further potential for cost savings and make the most energy efficient off-the-shelf storage technology tape systems. The current density demonstration is based on several important technical improvements.
25 times more data tracks on the unchanged 0.5 inch wide band could be accommodated through a precise positioning of the read and write heads. A great progress was also made in the detection ability of the individual bits, which allowed a 50 percent increase of the linear density. Another crucial factor was the use of a new, low-friction read and stylus. Almaden, this was developed research at IBM, based on close cooperation with FUJIFILM in the development of new storage media. IBM has had a long Tradition of innovation in tape storage technology. The first commercial IBM tape storage product, the IBM 726 magnetic tape unit was announced about 60 years ago. It also used band roles with a range of about a half an inch, reaching a capacity of approximately 2 megabytes.
Today announced band storage density would correspond to the 17.5 millions capacity of this first band role. (1) the record density was achieved at a typical speed of 2 meters per second, and the obtained error rates are correctable with standard error correction method and meet IBM’s specifications for LTO 4 products. (2) at this calculation, a 12-percent increase in the length of the band adopted the reduced Strip thickness from the results. 3) rounded up from 43.75 further information please refer to the English-speaking media release: news /… You can download high-resolution images online: photos/ibm.
