HP DLT/SDLT data cartridges offer high capacity and low cost per GB for customers who have already invested in DLT backup technology. The latest SDLT-II cartridges support DLTSage for optimized media and drive diagnostics. This allows IT managers and network administrators to better identify, predict, and proactively avoid backup errors. With DLTIce, cartridges can be formatted as WORM tapes, ensuring compliance with legal requirements for data storage and archiving. To increase capacity, SDLT II moves optical servo information to the second surface of the medium, thereby increasing the number of recording tracks on the data surface. HP DLT/SDLT media is well-suited for use with HP and other vendors' DLT/SDLT drives. A continuous testing program in HP's own media labs ensures that HP's unique quality standards are met optimally.
