Quick Answer: Fujifilm plans to spend roughly 10 billion yen (about $63 million) to raise its LTO tape output fivefold, measured against fiscal 2025 levels, between fiscal 2026 and 2028. The driver is archiving demand from generative AI, which is generating huge volumes of data that must be kept. Magnetic tape stays attractive because it stores large volumes cheaply and can be physically disconnected from the network, which makes it a strong defense against ransomware.
Most people assume tape died with the floppy disk. It didn't. Enterprise data centers and cloud providers never stopped using it, and now a major manufacturer is preparing for a surge. As Ars Technica reported, Fujifilm's announcement is one of the clearest signals yet that the old medium is getting a second act, and the reasons say a lot about how modern data is stored.
What Fujifilm Is Actually Building
The investment targets the Kanagawa Factory's Odawara site. Fujifilm describes it as the largest investment it has made to date in dedicated LTO tape facilities. The money will fund manufacturing expansion and additional personnel, with the work running from fiscal 2026 through 2028.
The product at the center of the plan is the LTO Ultrium10 cartridge. LTO stands for Linear Tape-Open, a format standard developed by a consortium of manufacturers, and Ultrium is the high-capacity branch of that family. Fujifilm's history with the format is long. It released its first LTO Ultrium tape in 2000, and in 2011 it became the first to commercially produce tape using barium ferrite magnetic particles.
The LTO-10 generation is notable for its magnetic chemistry. Fujifilm says it combines barium ferrite with strontium ferrite into what it calls "fine hybrid magnetic particles." Smaller, more uniform particles let engineers pack more data into the same physical area of tape. That is the core trick behind every LTO generation: more bits per square millimeter of tape, not bigger cartridges.
Why AI Is Driving Archive Demand
Here's the part that connects the headline to your own infrastructure. Generative AI doesn't just consume compute. It produces training corpora, model checkpoints, synthetic datasets, logs, and evaluation outputs, and organizations are increasingly told to keep them. Fujifilm calls the result "exponential growth" in data needs, and the company is betting that much of that data won't live on fast, expensive disk.
Most teams stop at "AI makes more data." The more useful question is which data needs to be kept and at what cost. Hot data, like active training sets, belongs on flash or disk. Cold data, like the raw archive you might need for an audit in five years, is where tape earns its keep.
The source notes that "major cloud service and data center operators" have expanded their tape use for exactly this reason: large volumes at relatively low cost.
The Air-Gap Argument Is Doing the Heavy Lifting
Cost explains why tape is on the shelf. Security explains why it's coming back into favor. Fujifilm highlights the ability to air-gap tape cartridges, and it frames this as a "last defense" against ransomware.
Consider a typical ransomware sequence. Attackers get domain admin credentials, reach the backup server, and encrypt or delete backups before anyone notices. Any backup that stays online and writable is exposed to the same attacker. A tape cartridge sitting in a vault, disconnected from the network, can't be reached by that attack path. Someone has to physically load it.
That's the mechanism, and it's why so many security teams specify offline copies in their 3-2-1 backup rule: three copies, two media types, one offsite. Tape is often the offline copy that makes that rule enforceable rather than aspirational.
Here's where most guides go wrong, though. Air-gapping is not a substitute for backup testing. A tape you can't restore from is just an expensive coaster. Test restores on a schedule, and check that your catalog and encryption keys are recoverable too.
Tape vs. Disk vs. Cloud: How to Choose
Tape isn't a universal answer. It trades speed for cost and isolation, and the right mix depends on how often you need the data back.
| Factor | LTO tape | Spinning HDD (nearline) | Cloud archive tier |
|---|---|---|---|
| Upfront cost per TB | Lowest of the three for large archives | Moderate | No hardware cost, but ongoing egress and retrieval fees |
| Access speed | Sequential; slow to locate and restore | Random access, fast | Retrieval can take minutes to hours, depending on tier |
| Offline isolation | Yes, physically disconnectable | No, always powered and networked | Depends on account and access controls |
| Power and maintenance | Near zero when stored | Continuous power and drive replacement | Handled by provider |
The trade-off is worth stating plainly. If you restore data weekly, tape's sequential access will frustrate you, and disk or cloud is the better fit. If you restore rarely but need certainty that the data exists and can't be altered, tape looks very good. Many organizations end up with a hybrid: disk for recent backups, tape for long-term retention, and cloud for geographic redundancy.
Most people stop here, and that's a mistake. The cloud line in the table hides a real caveat. Cloud archive tiers are often cheap to store in and expensive to retrieve from, so your actual cost depends on how often you pull data back.
The Caveats Nobody Puts in the Press Release
It's fair to say Fujifilm's announcement is a bet, not a guarantee. Capacity expansion depends on sustained demand, and the fiscal 2026 to 2028 timeline gives the company room to adjust if AI-driven archiving slows or changes shape.
There's also the matter of generations. The source notes that Gen 10 is the current technology, while Gen 11 through Gen 14 figures are consortium projections. Projections are useful for planning, but they aren't shipping products. If you're buying tape for a long retention window, check whether your drive generation will still be supported when you need to read those cartridges. Backward-compatibility rules in LTO are real, but they have limits, and drive generations do get retired.
Finally, expect a learning curve. Tape workflows require library management software, careful media rotation, and staff who know how to handle cartridges. Tools such as IBM Spectrum Protect or Veeam, which support tape targets, can automate much of this, but someone still has to own the process.
Frequently Asked Questions
What is magnetic tape storage used for today?
Magnetic tape storage is mainly used for long-term backup and archiving. Large enterprises and cloud providers use it because it holds large volumes at low cost per terabyte. Its key advantage is that cartridges can be disconnected from the network, which makes them useful as an offline copy against ransomware.
How does LTO-10 tape compare to earlier generations?
LTO-10 is the current generation, and each LTO release has increased both compressed and uncompressed capacity. It uses a hybrid of barium ferrite and strontium ferrite particles to store more data per unit area. Exact capacities for each generation are published by the LTO Consortium at lto.org.
Why is tape storage making a comeback?
Tape is making a comeback because data volumes are growing faster than budgets, and generative AI has accelerated that growth. Organizations need cheap, durable places to keep data they rarely touch. Tape's air-gap capability also helps it fit modern ransomware defense plans.
Can you use tape for AI training data?
Tape is best for cold data, such as archived datasets, model versions, and compliance records. Active training data needs fast random access, which disk or flash provides. Many teams keep working sets on disk and move completed datasets to tape once they're no longer in active use.
The Takeaway
The most actionable lesson is simple: treat magnetic tape storage as the offline layer in your data strategy, not as a legacy relic. Audit how much of your data is cold, estimate the restore frequency you actually need, and check whether an offline copy exists today. Try running one test restore from your oldest archive this week and note how long it takes. That single number will tell you more about your real storage costs than any vendor chart.
