By further developing new tape materials, coating technology and a surface-smoothing technology, Sony LTO4 offers a breakthrough in performance with a massive 800GB native and 1.6TB compressed maximum recording capacity.

For quicker backup and improved operating efficiency, LTO4 offers high-speed 120MB/s native and 240MB/s compressed data transfer.

To accommodate the LTO4 tape's thickness and long length, the reel accuracy has been improved. Optimized hub roundness contributes to stable operation and a new flange shape protects the tape edges. As in previous models, the LTO4 cartridge incorporates a robust non-contact 8KB IC memory with twice the capacity of previous generations.
