LTO stands for Linear Tape-Open. it is a magnetic tape data storage technology developed as an open alternative to the proprietary Digital Linear Tape . The technology was developed and initiated by Seagate, Hewlett-Packard, and IBM. The standard form-factor of LTO technology goes by the name "Ultrium".
In the late 1990s, Quantum's DLT and Sony's Advanced Intelligent Tape (AIT) were the leading options for high-capacity, high speed tape storage for PC servers and UNIX systems. Those technologies were and still are tightly controlled by their owners. Consequently, their availability was fairly limited. IBM, HP and Seagate sought to counter this by introducing a more open format. Much of the technology is an extension of the work done by IBM at its
