Imation's patented corner snap improves cartridge strength by keeping the leader pin in place & the cartridge tightly closed in the event of rough handling. A patented three-piece tape spool aids in tape guidance, distributing stress more evenly over the tape for better performance & longer archival life. 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. The new standard in high capacity, open-systems data storage Introducing Imation LTO Ultrium Generation 4 Tape Cartridges, manufactured with Imation's proprietary Tera Angstrom™ Technology. These next-generation 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.
