What is LTO-2 tape?
Just like LTO 1 the LTO-2 is a magnetic tape data storage technology developed as an open alternative to the proprietary Digital Linear Tape (DLT). The technology was developed and initiated by Seagate, Hewlett-Packard, and IBM. The standard form-factor of LTO technology goes by the name "Ultrium" or LTO 2 Ultrium tapes.
LTO-2 has 200 GB native capacity and has a transfer rate of up to 40 MB/s. Whilst LTO 1 tapes used RLL technology for encoding data, LTO 2 Ultrium tapes use PRML (Partial Response Maximum Likelihood). In addition, there are 512 tracks on an LTO 2 Ultrium tape whereas there are only 384 on LTO 1. Whilst LTO tapes are slightly smaller than most single reel tape cartridges, it also features LTO-CM (Cartridge Memory) which enhances functionality by providing a redundant file log as well as user defined information. An external reader provides instant access to this information without having to insert it into the tape drive. By specifying only those features needed for interchange of tape cartridges, the LTO Ultrium format retains flexibility. This flexibility allows for a substantial amount of implementation freedom with respect to performance characteristics, form factor, reliability, controllers, and interfaces - while tape cartridges remain interchangeable among LTO Ultrium tape drives.

LTO-1 In the 2000 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 Tucson lab during the previous 20 years. LTO tapes and/or
