Fujifilm develops new LTO Ultrium 10 data cartridge with 40TB capacity

Fujifilm expands its ecosystem of mass data storage on magnetic tape with the launch of the new LTO Ultrium 10 cartridge with a maximum recording capacity of 40 TB per cartridge (100 TB for compressed data).

The new LTO-10 will enable the secure and cost-effective storage of large volumes of information, responding to the growing demand for reliable data protection in the face of intensifying cyber threats.

The LTO-10 (40TB), available from January, is an advanced version of the Fujifilm LTO Ultrium 10 (30TB) data cartridge, which was launched in June 2025. Building on the success of LTO-10 (30TB), the new LTO-10 (40TB) cartridge incorporates the exclusive “fine hybrid magnetic particles” from Fujifilm to increase the recording density per area. In addition, the nano-coating technology used with a thin base coat of aramid film, allows the thickness of the tape to be reduced, increasing the length of tape per cartridge by 30%. This new 40TB cartridge is compatible with the same LTO-10 drive used for the 30TB cartridge.

On the other hand, the LTO-10 (40TB) data cartridge can be used in broader environmental conditions compared to models such as LTO-10 (30TB), thus expanding the recommended operating temperature and humidity range. The recommended temperature range goes from 15°C–25°C to 15°C–35°C, and tolerance to Relative humidity now supports up to 80% under conditions of 15°C–25°C, while LTO-10 (30TB) supports up to 50%. This improvement enables stable performance even in high temperature and humidity environments, making this format a versatile data storage medium, suitable for a variety of operating scenarios.

As ransomware attacks and other cyber threats put companies and organizations around the world at risk, protecting sensitive business data, customer information and research results has become a priority in all industries. Magnetic tape continues to be a reliable medium for storing large volumes of data, thanks to its stable read/write performance and the ability to physically isolate it from networks, as the data is decoupled from the network (“air gap”), the risk of data loss due to cyber incidents is significantly reduced. Therefore, magnetic tape is widely used by data centers and major IT companies for secure backup and archiving.

Demand for LTO tapes continues to grow, especially due to archiving capacity needs for AI. Capacity delivered on tape in 2024 reached a record 176.5 exabytes (a 15% increase from the previous year) underscoring the increasingly important role of the storage medium in data management.

Kenichi Otaki, director of data storage solutions at Fujidilm Corporation, states that “as the world's leading*5 manufacturer of magnetic tape cartridges for data storage, Fujifilm will continue to develop and supply high-performance, quality media that meets our customers' needs and builds their trust.”
