Linear tape open (LTO) is a magnetic tape technology based on linear recording on ½ inch wide tapes. Improvements in the fields of server technology, data compression, track layout and error correction code have created greater storage capacity, higher performance and better reliability. With a current compressed capacity of up to 30 TB (LTO-8), these cartridges are the first choice for data backup, restoration and archiving applications.

The Library Pack is a form of plastic packaging that provides protection against impacts, dust and moisture during transportation and handling. It has many benefits: it makes handling easy for use in automated systems, the transparent Library Pack allows the barcode label to be easily identified, and it prevents packaging waste. A Library Pack holds and protects 20 LTO tapes.

*The LTO-8 drive is able to initialize new LTO-7 media to an increased cartridge capacity of 9 TB native and 22,5 TB compressed instead of 6 TB and 15 TB in a LTO-7 drive. This cartridge is called LTO-7 type M media.
For the first time since the LTO format was introduced the LTO-8 specification is only backwards compatible with the former generation LTO-7. The new LTO-8 drives cannot read (and write) LTO-6 BaFe and LTO-6 MP media.

Instead of the usual metal particles, the use of magnetic barium-ferrite-particles (BaFe) increased archival life and performance through their chemical stability. From LTO-7 onwards all cartridges are produced with BaFe-particles.
