HP DLT/SDLT Data Cartridges offer high capacity & low cost per GB for customers with existing investments in DLT backup technology. HP SDLT II cartridges support DLTSage for enhanced media & drive diagnostics, enabling IT managers & network staff to better manage, predict & proactively prevent backup problems. DLTIce allows cartridges to be formatted as WORM tapes for compliance with regulations on data retention & archiving. To increase capacity, SDLT II transfers optical servo guide information to the other surface of the media, increasing the number of recording tracks on the data-bearing media surface. HP's DLT/SDLT media is exhaustively qualified for use with HP & non-HP DLT/SDLT drives. A continuous testing program in HP's media laboratory guarantees the high levels of quality uniquely specified by HP.
