Technology Overview HP LTO-3 Media
HP LTO-3 drives
Longer tape for greater storage capacity.
Twice the number of recording channels. The new drive writes 16 tracks of data simultaneously compared to 8 tracks for LTO-1 and LTO-2
Smoother basefilm achieves closer head-to-tape contact for high density recording.
Higher coercivity helps to resist the demagnetisation effect.
Thinner magnetic layer reduces demagnetisation loss to enable higher density recording.
Improved position error signal ensures better tracking of the servo head relative to the track centre.
» Accelerometer for reduced sensitivity to external vibration » T-reel hub and half moon machined as matched pair to reduce tracking disturbances caused by mating discontinuities » Roller shaft alignment improved by laser bending process » Roller coating improvements eliminate wear-in time » Real-time adaptation to tape tilt during writing Improved durability: » Tape lifter reduces head wear in severe, high usage environments
Increased margin between early warning end of media (EWEOM) and end of media (EOM). This means that data on a full tape will always fit on to the destination tape.

Improved tracking: Smaller magnetic particles achieve higher recording densities by reducing media noise at short wavelengths. This leads to a higher signal-to-noise ratio.

media and we’ve been disappointed in the reliability of some of the tape cartridges. NetBank’s experience is that HP’s technology actually does work better together. It provides superior quality and reliability across the entire disk and tape storage line. We are comfortable that HP tape media has a strong future for many years to come.” Todd Warnock, Director of Technology Services, NetBank Internet
Fully protect your data with HP LTO-3
LTO-3 Ultrium delivers high performance, ultra reliability and easy compliance for mission critical data centres. HP LTO-3 Ultrium media sets high standards in capacity and performance in the midrange tape market, with 800GB capacity per cartridge and transfer rates of 160MB/sec.*.

Since late 2003, second and third generation LTO products have gained significant market momentum. Tape storage is essential for best practice data protection strategies and achieving total cost of ownership goals. Large capacities, high transfer rates, full standardization, a well-articulated migration path, high reliability and a competitive environment contribute to the popularity of LTO technology.
