The Cold Storage Comeback: Fujifilm Bets Big on LTO Tape to Fuel AI Data Needs

While high-performance chips grab the headlines, the massive data requirements of generative AI are driving a massive production scale-up for magnetic tape.
In the rush to build the next generation of AI, the industry's focus is typically on the compute side of the equation. However, the sheer volume of data required for AI training and inference is creating a massive demand for archival storage, leading to a surprising revival of the magnetic tape drive.
**Fujifilm's Massive Capacity Bet** Fujifilm announced Thursday that it will invest approximately 10 billion yen (roughly $63 million to $64 million) to increase its magnetic tape production capacity fivefold. According to reporting from Ars Technica, this investment targets the company's Odawara site at the Kanagawa Factory and represents the largest investment Fujifilm has ever made in dedicated LTO tape facilities. The expansion project is scheduled to run from fiscal years 2026 through 2028.
Fujifilm attributes this surge to the "exponential growth" in worldwide data needs driven by the spread of generative AI and cloud services. The company noted that creating secure and efficient environments to store the enormous amounts of data accumulated through AI training and inference is now critical to supporting a digital society.
**The Tech: LTO-10 and Beyond** The production boost is primarily focused on the "FUJIFILM LTO Ultrium10" tape. As reported by The Register, LTO-10 tapes offer native storage capacities of either 30TB or 40TB and transfer data at 400 MB/s, though many users employ compression to more than double that capacity. Ars Technica notes that the LTO Ultrium10 is the first in the medium to utilize "fine hybrid magnetic particles," combining strontium ferrite and barium ferrite technologies.
While LTO is the only surviving non-proprietary tape format—maintained by the LTO Program consisting of IBM, HPE, and Quantum Corp—it is not without its hurdles. The Register reports that LTO cartridge shipments actually declined in 2025, dropping to 160.3 exabytes from a record 176.5 exabytes in 2024, a dip the LTO Program blamed on difficult macro-economic conditions. However, the program predicts record sales for 2026.
**Why Tape Still Matters** Despite the slow access times associated with offline or nearline archives, tape remains a staple for cloud giants and data center operators due to its low cost for large-scale storage. Beyond the price point, Fujifilm highlights a critical security advantage: the air-gap. Because tape cartridges can be physically disconnected and stored in vaults or separate facilities, they serve as a primary defense against sophisticated cyberattacks and ransomware.
**The Roadmap** Looking ahead, the LTO Program has defined four future generations of the format, with updates typically arriving every four years. According to projections cited by The Register: * **LTO-11 (est. 2029):** 70TB capacity * **LTO-12:** 120TB capacity * **LTO-13:** 210TB capacity * **LTO-14:** 365TB capacity
One significant shift in compatibility has occurred: while previous LTO drives could read multiple past generations, LTO-10 devices can only read the current generation of tapes.
