What is LTO tape?
LTO (Linear Tape-Open) is a tape standard developed by HP, IBM, and Seagate as a competitor to DLT.
LTO tape stores data in 384 data tracks which are divided into four data bands of 96 tracks each.
The four data bands are bordered by bands of servo information which are written during tape manufacture.
Data bands are filled one-at-a-time, in a linear fashion.
LTO tapes contain 4KB of non-volatile memory which can be read through a non-contacting passive RF interface. This storage space contains data about the tape and can be read without the time required to read the magnetic tape itself.
LTO Tape Generations
The LTO tape standard is designed to last for four generations of magnetic tape technology.
| LTO Tape Generation | Uncompressed Capacity |
|---|---|
| Generation 1 | 100GB |
| Generation 2 | 200GB |
| Generation 3 | 400GB |
| Generation 4 | 800GB |
LTO Tape Physical Specifications
An LTO tape is approximately 4.1" x 4.0" x 0.8".
LTO Alternatives
Alternative tape storage standards to LTO include DLT and AIT.
