Only the full length 100 GB tapes were produced. The first generation of Ultrium tapes were going to be available with four types of cartridge, holding 10 GB, 30 GB, 50 GB, and 100 GB. In common usage, LTO generally refers only to the Ultrium form factor.

As of 2008, LTO Ultrium was very popular and there were no commercially available LTO Accelis drives or media. The real-world performance never exceeded that of the Ultrium tape format, so there was never a demand for Accelis and no drives or media were commercially produced. IBM's (short-lived) 3570 Magstar MP product pioneered this concept. The other proposed format was Accelis, developed in 1997 for fast access to data by using a two-reel cartridge that loads at the midpoint of the 8 mm wide tape to minimize access time. Initial plans called for two LTO formats to directly compete with these market leaders: Ultrium with half-inch tape on a single reel, optimized for high capacity, and Accelis with 8 mm tape on dual reels, optimized for low latency.Īround the time of the release of LTO-1, Seagate's magnetic tape division was spun off as Seagate Removable Storage Solutions, later renamed Certance, which was subsequently acquired by Quantum.ĭespite the initial plans for two form-factors of LTO technology, only Ultrium was ever produced.

Much of the technology is an extension of the work done by IBM at its Tucson lab during the previous 20 years. To counter this, IBM, HP and Seagate formed the LTO Consortium, which introduced a more open format focusing on the same mid-range market segment. Consequently, there was little competition between vendors and the prices were relatively high. These technologies were (and still are) tightly controlled by their owners.

Sony followed this success with their own now-discontinued 8 mm data format, Advanced Intelligent Tape (AIT).īy the late 1990s, Quantum's DLT and Sony's AIT were the leading options for high-capacity tape storage for PC servers and UNIX systems. In the late 1980s, Exabyte's Data8 format, derived from Sony's dual-reel cartridge 8 mm video format, saw some popularity, especially with UNIX systems. DEC originally called theirs CompacTape, but later it was renamed DLT and sold to Quantum Corporation. IBM called its format the 3480 (after the 3480, the one product that used it) and designed it to meet the demanding requirements of its mainframe products. Although the physical tape was nominally the same size, the technologies and intended markets were significantly different and there was no compatibility between them. In the mid-1980s, IBM and DEC put this kind of tape into a single reel, enclosed cartridge. Half-inch ( 1⁄ 2-inch, 12.65 mm) magnetic tape on open reels has been used for data storage since the 1950s, with the IBM 7 track.
