Please find below the choice of LTO tape drives currently available. In addition to this you might like to click on the tape technologies for information regarding what each tape technology offers.

Linear Tape-Open (LTO) technology was developed jointly by HP, IBM and Quantum to provide a clear and viable choice in an increasingly complex array of tape storage options

LTO technology is an "open format" technology, which means that users will have multiple sources of product and media. The "open" nature of LTO technology also provides a means of enabling compatibility between different vendors' offerings.

The Ultrium format is the "high capacity" implementation of LTO technology.
