The LTO tape format was developed as a substitute to the DLT tape format. This open tape standard was developed and proposed by IBM, Seagate and HP. Performance, durability and output level has been enhanced in the LTO format as it combines the benefits of error correction, data compression, multi-channel, and servo technology and track layout. Ultra thin film is utilized in the LTO tape format that generates uniform magnetic particles. These sub micron sized magnetic particles ensure stability and generate strong signal output; both these features of LTO tape format are helpful in high density recording. The most essential key feature of LTO tape format is stable tape traveling. Lateral strength and dimensional change rates have been dramatically enhanced of the base films now used in LTO tape format. The lateral strength has been improved by 45% and dimensional rates by 60%. LTO technology is more advantageous as during tape travel, spacing gaps are not produced between head block and tape travel. LTO tape format has set new standards because of its optimized head tape interface.

Transfer speed and capacity of the LTO4 ultrium format have been enhanced to deliver higher performance. The transfer rate of LTO-3 tape technology is 160MB/sec which has been enhanced to 240MB/sec in the LTO 4 tape technology. The WORM technology is featured in LTO 3 as well as the LTO-4 tape technology. WORM is a cost efficient technology that records information onto the media in non-rewriteable format that assists in addressing the compliance requirements. LTO tape format has set new standards because of its optimized head tape interface.
LTO 4 ultrium incorporates extra security features such as the encryption technology of 256 bit AES-GCM. This specifically developed encryption technique provides drive level encryption that records encrypted information onto the LTO tape media. In this way the recorded data is protected and the users can move sensitive data without any fear and worries. LTO-4 tape format protects the enterprise's investment and provides the luxury of backward compatibility. LTO 4 tape format can recover and store non-encrypted information form the LTO3 tape cartridge while it can read information from the second generation LTO 2 tape cartridge. LTO technology is more advantageous as during tape travel, spacing gaps are not produced between head block and tape travel.
Numerous license packages are offered by the LTO program. These packages include basic packages that are related to the guidelines & specification for interchangeability up to the enhanced license packages related to the licenses and specifications to manufacture the LTO tape products. LTO ultrium is a single reel format whose target market are those customers that require high capacity and fast data restore and backup capabilities. The compressed recording capability of single LTO 4 cartridge reaches 1.6 terabytes while the native transfer speeds are between 80 and 160MBps. LTO tape format has set new standards because of its optimized head tape interface.
