The Ultrium tape format specification is LTO Technology optimized for high capacity and performance. The Ultrium format uses a single-reel tape cartridge to maximize capacity, and is ideally suited for backup, restore and archive applications. The format is user-agnostic, meaning that it addresses a wide variety of needs from a single-server user to complex multiple server enterprise environments.

LTO-based products are not compatible with non-LTO tape products. The LTO Program created a competitive environment with multiple vendors offering unique features while maintaining data interchange among competing LTO offerings.

The Ultrium format trademark identifies products that have passed annual third-party compliance verification to ensure compliance with the Ultrium tape format specification. Use of this trademark is granted only after an Ultrium tape format product has passed the compliance verification testing process.

The LTO Program provides a roadmap of expected technology and performance targets so that our licensees and their customers can adequately plan their technology offerings and purchasing. The roadmap represents intentions and goals.

LTO Ultrium drives up to generation 7 can read data from a cartridge in its own generation and two prior generations, LTO-8 Ultrium drives can only read LTO-8, LTO-7 and LTO-7 Type M media. An Ultrium drive can write data to a cartridge in its own generation and to a cartridge from the immediate prior generation (in the prior generation’s format).

For example:

An Ultrium format Gen. 7 drive will read and write data on an Ultrium format Gen. 7 (in the Gen 7 format) and 6 cartridge (in the Gen. 6 format) and read data on an Ultrium format Gen. 5 cartridge.
An Ultrium format Gen 8 drive will read and write data on an Ultrium format Gen 8 and Gen 7 cartridge (in the Gen 7 or Type M format).

An open tape format specification is one that is readily available to all potential manufacturers and offers licenses for the IP (Intellectual Property) at a reasonable investment. The competitive environment fostered by multiple sources of product can lead to faster paced innovation and enhancements, and can generally mean competitive prices and greater data compatibility.

HPE, IBM and Quantum each provide expert knowledge of customer needs and complementary solutions that provide for the best technology while promoting a strong foundation for data interchange.  The companies also provide marketing support for the LTO format and encourage other companies to participate in this tape industry opportunity through the open licensing process.

Tape industry fragmentation over-complicates buying decisions for customers. With this in mind, HPE, IBM and Quantum are delivering technology that serves multiple needs for data storage  supported by multiple suppliers.

LTO cartridges should be kept at room temperature and inside their original cases. Tape cartridges must be maintained within specific environmental specifications in terms of temperature, humidity and magnetic fields for proper operation and optimal performance. These specifications are printed on the information sleeve that comes with the cartridge. Vertical storage positioning is recommended for tape cartridges. While it is a good practice to re-wind LTO tapes on a yearly basis, it is not required if the cartridges are properly stored.

Magnetic recording media are not affected by x-rays. It’s important to note, however, that some international airports are now using magnetic devices to inspect luggage. This type of device or other devices emitting stray magnetic fields may affect magnetic media. If it’s permitted in the country you’re visiting, you should hand carry your material through airport security and ask for a non-magnetic inspection.
