Magnetic tape storage: Fujifilm plans to have 384 TB capacity by 2030

Fujifilm plans to use strontium ferrite for future magnetic tape storage. This should enable capacities of up to 400 TB to be achieved.

Magnetic tape storage continues to play an important role in the data center area as an archive and backup solution. Current LTO-8 variants offer up to 12 Tbytes of storage space in a compact format with less susceptibility to errors than HDDs and SSDs. With Sony and Fujifilm there are currently only two licensees.

Sony and IBM last reported significant successes in efforts to steadily expand the capacity of their cartridges in 2017 . At that time, the storage density in the laboratory was increased to accommodate 330 TB in the format used. Fujifilm meanwhile has a counter-strike and considers up to 400 TB possible.

From 2030 onwards, Fujifilm’s magnetic tape storage (LTO-13) with capacities of up to 384 TByte is expected to reach the mass market. Various intermediate steps are planned beforehand. In the previous generations, the capacity should double every 2 to 3 years. Magnetic tape storage up to 24 TB is planned for this year. As a result, it will become 48 TB in 2022.

Fujifilm specifies products with up to 192 TB at least for the time being on its own roadmap. They have been set as standards since 2017. However, the time from standardization to commercial launch is very long for magnetic tape storage. For example, the standard for the LTO-9 storage with up to 24 TB that was envisaged this year was already adopted in 2014.

Magnetic tape storage with up to 384 TB and 768 TB (LTO-13 and LTO-14) is expected to go through the standardization process in the coming year. At Fujifilm, the technological basis for the two planned generations is strontium ferrite as a new material. Current magnetic tape storage devices are based on barium ferrite, the maximum capacity of which will be exhausted with the upcoming LTO-9. The coming generation LTO-10 should initially use a hybrid solution made of barium ferrite and strontium ferrite, while the complete switchover with the LTO-11 is planned in 2025.

A suitable replacement must then be found for the LTO-14 cassettes, because the possibilities of strontium ferrite are also limited. At Fujifilm, one expects to fully exhaust the limit at 400 TB in the appropriate format.
