Linear Tape-Open (LTO)
A type of tape storage technology that is developed by the IBM Corporation, Hewlett-Packard, and
Quantum. LTO technology is an "open format" technology, which means that its users have multiple
sources of product and media. The "open" nature of LTO technology enables compatibility between
different vendors' offerings by ensuring that vendors comply with verification standards. The LTO
technology is implemented in two formats: the Accelis format focuses on fast access; the Ultrium
format focuses on high capacity. The Ultrium format is the preferred format when capacity (rather
than fast access) is the key storage consideration. An Ultrium cartridge has a compressed data
capacity of up to 30 TB (2.5:1 compression) and a native data capacity of up to 12 TB.
