The HP StorageWorks SDLT Tape Drive is a high-capacity, high-performance streaming tape drive designed for use with HP ProLiant servers, HP AlphaServers, and Open SAN storage systems. The tape drive uses Laser Guided Magnetic Recording (LGMR) technology to maximize the amount of data that can be stored on a tape. The SDLT uses a clustered magnetic-resistive (MR) head technology to improve data density, uses Partial Response Maximum Likelihood (PRML) technology to provide increased performance, and has a robust tape buckling system for reliability.
