Imation Ultrium LTO 4 Tape Cartridges combine the advantages of linear, multi-channel, bi-directional formats with enhancements in servo technology, data compression, track layout & error correction. The result is an exciting new media that delivers outstanding performance & twice the capacity of LTO Generation 3 cartridges. Features Robust Cartridge Construction The patented corner snap keeps the leader pin in place & the cartridge tightly closed to prevent error-causing debris from entering the cartridge, thus helping to ensure that the tape flows evenly for maximum read/write capability. The unique three-piece tape spool design distributes stress more evenly over the tape compared to two-piece spools. This cartridge construction keeps the tape flat, helping protect data across the entire tape. Exceptional Performance & Quality A proprietary servo-writing process optimizes tape tracking & helps ensure accurate read/write operations, enabling best-in-class Position Error Signal (PES) performance to minimize servo off-track errors & improve overall transfer rates. Security & Protection Ultrium LTO 4 drives offer hardware-based 256-bit data encryption, providing the highest level of security without any loss of performance; WORM (Write Once Read Many) cartridges are also available.
