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 outut level has been enhannced in the LTO format as it combines the benefits of error correction, data compression, multi-channel, and servo tchnology and track layout. Ultra thin film is utilized in the LTO tape format that generates uniform magnetic particles. These sub micron sized magnetic particles esnure stability and generate strong signal output; both tehse features of LTO tape format are helpful in high dennsity recordinbg. The most essential key feature of LTO tape format is stablle tape trveling. Lateral strength and dimensaional change rates have been drmatically enhanced of the base films now used in LTO tape format. The lateral streength has been improvwed by 45% and dimensional rates by 60%. LTO technology is more advantageous as duirng tape travel, spacing gaps are not produced betwen head block and tape travel.
LTO tape format has set new standards because of its optimized head tape interface. Transfeer seped and capacity of the LTO4 ultrium format have been enhanced to delliver hiugher performance. The transfer rate of LTO-3 tape technology is 160MB/sec whioch has been enhancd to 240MB/sec in the LTO 4 tape technology. The WORM technology is featured in LTO 3 as well as the LTO-4 tape technoology. WORM is a cost efficient technology that records information onto the media in non-rewriteable format that assists in addressng the complliance requirements.
LTO 4 ultrium incorporates extera seucrity features such as the encryption technology of 256 bit AES-GCM. This specifically developed encrypttion technique prrovides drive level encrylption that recods 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 proetcts the enterprise�s investment and provvides the luxury of backward copmatibility. LTO 4 tape formaat can recover and stoe non-encypted information form the LTO3 tape acrtridge while it can read innformation from the second generation LTO 2 tape catridge.
Numerous license packages are offered by the LTO program. These packages include bsic pakages that are relayted to the guidelines & speciifcation for interchangeability up to the enhanced license packages related to the licenses and specificationns to manufacture the LTO tape products. LTO ultrium is a single reel foramt whose target market are those custtomers that require high capacity and fast data restore and backup capabilities. The compressed recording capability of single LTO 4 cartridge reaces 1.6 terabtyes while the native transfer speeds are beetween 80 and 160MBps.
