Lto Tapes

in Tape
Linear Tape-Open (or LTO) is a magnetic tape data storage technology originally developed in the late 1990s as an open standards alternative to the proprietary magnetic tape formats that were available at the time. Hewlett-Packard, IBM and Certance (at that time the removable storage systems division of Seagate Technology and now Quantum Corp.) initiated the LTO Consortium, which directs development and manages licensing and certification of media and mechanism manufacturers. The standard form-factor of LTO technology goes by the name Ultrium, the original version of which was released in 2000 and could hold 100 GB of data in a single cartridge. The most recent version was released in 2010 and can hold 1.5 TB in the same size cartridge. Since 2002, LTO has been the best selling "super tape" format and is widely used with small and large computer systems, specially for backup.
LTO introduced as a powerful and scalable open tape architecture aimed at meeting the rising storage demands of contemporary servers.LTO tapes are mainly for intensive usage in libraries and long-term storage for archival purposes. Considering such high usage environments, the strength and durability of the cartridge is very important as well as that of the data tape itself.

LTO data tapes have a 100 GB native and an 800 GB compressed storage capacity. That's more than any DVD can store.Since 2002, LTO has been the best selling "super tape" format and is widely used with small and large computer systems, especially for backup.

LTO1, LTO2, LTO3, and LTO4 stand for the size of the GB storage capacity. The bigger the LTO number, the bigger the capacityThe LTO form Ultrium is a half-inch magnetic tape with a single reel (contrasting with the 8mm double reel Accelis). The Ultrium was developed as a drop-in replacement for the DLT (developed by Digital Equipment Corporation and now owned by Quantum).

LTO Ultrium tape uses a single reel to maximize storage capacity and thus is better suited for archival use. An Ultrium LTO drive is also backward compatible and contains a strong error correction algorithm that makes data recovery possible when lost data is within one track or up to 32 mm of the tape medium.


The is very popular and LTO in common usage usually refers to the LTO Ultrium as the LTO Accelis are no longer commercially available. Some of the more popular LTO tapes are: The 183800 and LTX100G LTO-1 tape. The 183850, MR-L5MQN-01 and C7972A LTO-2 tape. The 183900, LTX400G and C7973A LTO-3 tape. The 183906 and 26592 LTO-4 tape.
