While electronic data generation continues to grow at an 80% annual rate globally, according to IDC, the tape industry is keeping pace with the introduction of larger capacity, faster data transfers, and more scalable products that provide even better returns on investment that provides the protection of your business' data. Unlike their magnetic disk cousins (where the understood physical limits of the medium are continually being challenged and redefined) tape manufacturers have proven that there is at least another 16-fold capacity increase possible by using technologies and materials that are already being tested in their labs.

It is well established that tape is the most cost-effective media for storing large amounts of data. And even as disk capacities have dramatically increased over the past 10 years, the tape industry has continually maintained a capacity advantage over disk; a single tape cartridge can be used to backup the contents of a single hard drive. This has always been the case, and it continues to be the driving imperative behind tape drive and media development.

The science behind the improvements in tape technology is very impressive, and also very technically sophisticated. Over 40 researchers representing the major tape drive manufacturers, tape media suppliers and many of the leading research universities, collaborated (as part of the Information Storage Industry Consortium--INSIC) to analyze enterprise tape market requirements. The result was the development in 2001 of a 10-year projection for the future of magnetic tape storage. INSIC's work indicates that to remain an economically viable storage solution when compared to disk, tape capacity must grow at a rate comparable to future disk capacity growth on a cost-per-gigabyte basis.

Although disk densities are continuing to rise, the rate of growth is expected to slow as disk recording nears a superparamagnetic limitation. Due to a much lower areal recording density and much greater recording area, tape technology has the potential to grow at a faster rate and as a result improve its cost per gigabyte trends compared to disk. Therefore, when combined with disk in the enterprise storage environment, the tape industry roadmap currently maintains that tape capacity on a single cartridge must achieve 10 terabytes (TB) uncompressed per cartridge by 2011, and must reach 1TB uncompressed on a single cartridge by 2006 on its way to reaching the 10-year goal.
