Shock resistance enhanced by ultrasonic-welded shell caseIn addition to screws, we use ultrasonic welding to fasten the sidewalls of the door opening for improved ruggedness. This protects the case against damage from drop impact and protects valuable data.
High-speed rotation technologyLubricant-impregnated POM plastic is used for the reel center that contacts the cartridge's upper shell when the tape reel rotates, ensuring high-speed reel rotation with optimal sliding and friction characteristics. This allows accurate reading and writing of data on the tracks.
High-strength shell tested by rigorous drop impactProprietary tests involving 75 cm drops onto plastic tiles at different orientations helped develop a thoroughly rugged, reliable cartridge.
Clear and simple write-protect switchMoving the red switch right and left enables or blocks recording. A lock-shaped switch allows fast identification of write-protect status, helping to safeguard against erroneous operations.
Metal reel core and reel lock mechanismFor the reel core, we used a metal material especially susceptible to magnetic attraction to achieve chucking forces capable of withstanding high-speed rotation.
A reel lock on the tape reel fits into the upper shell to lock the reel into position. The reel lock is designed to engage deeply to prevent reel misalignment even when the reel is subjected to physical shock during transport or when stored vertically for long periods in a library.
Hub-shaped support structure to withstand tape pressureThe support provided by the structure of the reel flange guards against deformation of the hub by tape winding pressure, helping the tape resist deformation in a long-term storage environment.

To correspond with further high-density recording by shortening the recording wavelength, LTO4 adopts newly 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. By introducing newly-developed tape surface-smoothing technology, Sony improved the tape surface.
Sony improved the tape surface while also realizing noise reduction and boosting output in the high frequency range.
LTO4 realized high recording capacity by utilizing thinner tape (LTO3 ： 8.0μm→LTO4 ： 6.6μm) to allow a longer tape length (LTO3 ： 680m→LTO4 ： 820m).
Due to the increased number of data tracks (LTO3 ： 704→LTO4 ： 896) 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 newly-developed high accuracy cutting technology, Sony LTO4 realizes high stability under various operating conditions.
We use Advanced Alloy Armored Metal Particle, a special magnetic material developed from proprietary Sony technology. Uniformly coated with alloy and ceramics, the material surface provides high-output characteristics while maintaining outstanding weather resistance. Compared to conventional materials, the Advanced Alloy Armored Metal Particle significantly reduces variations in particle size. We also use a super orientation technology that orients particles in the same direction to minimize noise. Ultra-thin magnetic film technology made it possible to form magnetic coatings containing uniform, submicron-size particles for high signal output and stability in high-density recording.
Translatory tape travel is one of the most important elements of linear formats such as LTO. For the most part, true tracking is determined by tape quality, particularly the mechanical strength of the base film, the primary tape material. For the LTO base films, we improved dimensional change rates and lateral strength by 60% and 45%, respectively. Conventional tapes pose a problem involving spacing gaps between the tape and head block during tape travel; this gap has been removed to achieve an optimum head tape interface.

Highly Accurate Servo SignalsOur high-output and high S/N tapes, combined with Sony's original servo writer, provide highly accurate signals. In the LTO format, the head block is positioned by the guidance of signals from the servo track during data recording and playback. Sony LTO uses highly accurate servo signals to improve data reliability by preventing off-tracks during reads and writes. |
Reduced tracking errorsSince LTO4 has a very thin magnetic layer, a decrease of servo signal output recorded on tape was a concern. Despite thin magnetic layer (approx. 0.1μm), 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 (6.6μｍ) 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. |
