Sony's LTO 4 tape cartridges feature a storage capacity of 800GB native (1.6TB compressed) and transfer rate of 120MB/second native (240MB/second compressed). Sony's LTO 4 cartridges represent the highest performance in the LTO category of products. Armed with A3MP technology, superior tracking stability and an ultrasonically welded shell, Sony LTO 4 maximizes your data protection.
By further developing 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.
High-performance data cartridge
To accommodate the LTO4 tape's thinness and long length, the reel accuracy has been improved. Optimized hub roundness contributes to stable operation and a flange shape protects the tape edges.
High-density recording with low error rate
To correspond with further high-density recording by shortening the recording wavelength, LTO4 adopts developed fine magnetic particles. Further optimizing the dispersing technology for LTO4, Sony realized high dispersion and high packing density on newly developed fine magnetic particles that are approx. 70% the volume of LTO3. Sony improved the tape surface while also realizing noise reduction and boosting output in the high frequency range.
High stability of base film against elongation and shrinkage
LTO4 realized high recording capacity by utilizing thinner tape to allow a longer tape length. Due to the increased number of data tracks and narrowed track width, higher stability of the base film against elongation and shrinkage is required. By optimizing the strength balance of the base film and adopting the high accuracy cutting technology, Sony LTO4 realizes high stability under various operating conditions.
Reduced tracking errors
Since LTO4 has very thin magnetic layer, a decrease of servo signal output recorded on tape was a concern. Despite thin magnetic layer Sony realized high stable servo signal output by employing bias recording theory to optimize servo recording signal control. With the increase of the number of data tracks, more accurate tracking technology is required. Sony realized stable operation on the thin and smooth tape with a servo writer corresponding to high-density tracking that Sony developed for LTO4 format, achieving high-quality magnetic servo signal writing. The result is significantly improved data writing and reading accuracy.
