Fujifilm develops LTO Ultrium 10 data cartridge with 40TB capacity

Fujifilm expands its mass data storage ecosystem 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 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.

LTO-10 (40TB), available for shipping beginning January, is an advanced iteration of the Fujifilm LTO Ultrium 10 (30TB) Data Cartridge (LTO-10 (30TB)), which was launched in June 2025. Building on the success of LTO-10 (30TB), the new LTO-10 (40TB) cartridge incorporates Fujifilm’s proprietary “fine hybrid magnetic particles” to enhance areal recording density. Additionally, a novel thin-layer technology with Aramid film reduces tape thickness, allowing a 30% increase in tape length per cartridge. This new 40TB cartridge is compatible with the same LTO-10 drive hardware as used for the 30 TB cartridge.

Furthermore, the LTO-10 (40TB) has expanded its recommended operating temperature and humidity range compared to current models such as the LTO-10 (30TB). The temperature range has been extended from 15°C–25°C to 15°C–35°C, and the humidity tolerance now supports up to 80% (under conditions of 15°C–25°C). This enhancement enables stable performance even in high-temperature and high-humidity environments, making it a versatile data storage media suitable for a wide variety of operational settings.

As ransomware and other cyberattacks increasingly threaten enterprises and organizations worldwide, safeguarding sensitive business data, customer information, and research results has become a top priority across industries. Magnetic tape remains a trusted medium for large-scale data storage due to its stable read/write performance and ability to be physically isolated from networks—creating an “air gap” that significantly reduces the risk of data loss from cyber incidents. Consequently, magnetic tape is widely adopted by data centers and major IT companies for secure backup and archiving.

Shipments of magnetic tape, primarily used for data backup, have grown at an annual rate of over 10% since 2020 and are expected to continue increasing*5, driven by the growing need for AI-ready archival capacity. The demand for LTO tape continues to expand, underscoring its critical role in modern data management.

Kenichi Otaki, the head of data storage solutions, Fujifilm Corporation, says “as the data storage cartridge manufacturer with the top global market share,*6 Fujifilm will continue to develop and supply high-performance and high-quality media that meet the needs of our customers and build their trust.”
