What is LTO?

LTO (Linear Tape-Open) is a tape standard developed by Hewlett-Packard, Seagate, and IBM as an alternative to DLT.

LTO tapes store data in 384 data tracks which are divided into four data bands of 96 tracks each.

The four data bands are seperated by bands of servo information which are written while the tapes are being manufacture.

Data bands are filled one-at-a-time, in a linear fashion.

LTO tapes also contain 4KB of non-volatile memory which can be read through a non-contacting passive RF interface. This memory stores data about the tape and can be read much more quickly than the time required to read the magnetic tape itself.

LTO Tape Generations

The LTO tape standard is designed to last through four generations of magnetic tape technology:

LTO Tape GenerationUncompressed Capacity
Generation 1100GB
Generation 2200GB
Generation 3400GB
Generation 4800GB

LTO Tape Physical Specifications

An LTO tape measures approximately 4.1" x 4.0" x 0.8".

Alternatives to LTO

LTO alternatives include DLT and AIT.
