Fortuna Data & HoloMem
Fortuna Data is working with HoloMem — the UK-based holographic storage innovator — to bring next-generation optical archival technology to enterprise organisations. Talk to us about what this means for your long-term data strategy.
What is Holographic Data Storage?
Holographic data storage is a technology that encodes digital information using light patterns across the entire volume of a recording medium — rather than just along its surface as magnetic and optical disks do. By using laser interference to write data in three dimensions, holographic storage achieves storage densities and longevity that conventional media cannot match.
Where traditional media stores data bit by bit along tracks or blocks, holographic storage uses interference patterns generated by lasers to encode information throughout the full depth of the material. Each pattern can represent millions of bits simultaneously — enabling parallel read and write operations at extraordinary speeds.
How Holographic Storage Works
The fundamental principle behind holographic data storage is the use of two laser beams — a signal beam carrying the data and a reference beam — which intersect inside a photosensitive recording material. The resulting interference pattern encodes the data as a hologram within the volume of the medium.
To read the data back, the reference beam alone is shone into the material. The stored hologram diffracts the light to reconstruct the original data pattern, which is then captured by a detector array. Because the entire page of data is read in parallel, retrieval speeds can be extremely high.
Multiple holograms can be stored in the same physical space by varying the angle, wavelength, or phase of the reference beam — a technique called multiplexing. This is what gives holographic storage its extraordinary density advantage.
Surface-based recording
- Data stored on surface only
- Sequential bit-by-bit writing
- Limited by track density
- Magnetic degradation over time
- Physical media wear from rewrites
- Typical lifespan 10–30 years
Volumetric recording
- Data stored through full volume
- Parallel page-based writing
- Density scales with depth
- No magnetic degradation
- No mechanical read/write heads
- Potential lifespan 100+ years

HoloMem was founded by Charlie Gale, an inventor with a background in optical technology and product innovation. Gale spent nearly a decade at Dyson working on disruptive technology prototyping before turning his attention to a fundamental question: how much data could be embedded within holographic structures, and at what density?
The breakthrough came through Gale's earlier work on holographic authentication labels — the shimmering holograms found on banknotes and electronics packaging. His team discovered that instead of simply displaying a visual hologram, these optical structures could contain machine-readable, stacked data layers. The question of how many layers could be stacked, and how small they could become, opened the door to holographic data storage as a practical enterprise technology.
HoloMem is developing holographic optical storage specifically designed for the long-term preservation of massive datasets — targeting the organisations that need to store data reliably for decades, not just years.
Why the Industry Needs This Technology Now
The global demand for long-term data storage is growing faster than existing technologies can sustainably support. Several converging trends are driving this pressure:
AI and machine learning datasetsTraining data for AI models is growing exponentially. Organisations need to retain vast historical datasets for model retraining and auditability — often for years or decades.
High-resolution video and imaging4K and 8K media, medical imaging, satellite data, and scientific instrumentation are generating data volumes that dwarf previous generations.
Regulatory retention requirementsFinancial services, healthcare, legal, and public sector organisations face increasingly long mandatory data retention periods under UK and international regulations.
Historical analytics and insightOrganisations are retaining more data for longer as the value of historical datasets for analytics and business intelligence becomes better understood.
National archives and heritageLibraries, museums, government archives, and scientific institutions need to preserve digital assets across generational timescales — beyond what any current medium reliably delivers.
Evolution, Not Replacement
One of the most important points Charlie Gale makes in his conversation with Fortuna Data's Ray Quattromini is that holographic storage should be understood as an evolution in archival technology — not an immediate replacement for established systems.
Tape, disk, flash, and cloud will continue to play essential roles across different workloads for the foreseeable future. Magnetic tape in particular remains an extremely effective technology for cold archival storage — offering low cost per terabyte, long media life, and air-gapped security that makes it resilient to ransomware attacks.
What HoloMem is developing is a complementary tier — specifically designed for the scenarios where existing technologies face their greatest limitations: extreme density requirements, century-scale longevity, and zero mechanical degradation.
Extraordinary density
Data stored in three dimensions rather than two — multiple layers in the same physical space using multiplexing techniques.
Century-scale longevity
Optical media engineered for archival stability — no magnetic degradation, no mechanical wear, stable for decades under correct conditions.
No mechanical wear
No read/write heads in contact with the medium. Data is written and read using light — eliminating the physical degradation of repeated access.
Parallel data access
Entire pages of data read simultaneously rather than bit by bit — enabling high retrieval speeds despite the archival nature of the medium.
Sustainable storage
Lower ongoing energy requirements than spinning disk or data centre-based cloud storage for cold archival workloads.
Complements existing tiers
Designed to work alongside tape, disk, and cloud — not replace them. Adds a new tier optimised for extreme long-term preservation.
What This Means for UK Businesses
Holographic storage is not a consumer technology — it is being developed specifically for enterprise and institutional use cases where existing technologies face genuine limitations. For organisations managing large volumes of data that must be retained reliably for extended periods, this represents a significant development.
Fortuna Data is tracking this technology closely and working with HoloMem to understand how it will integrate into enterprise storage architectures. We are positioned to advise UK organisations on where holographic storage fits within their broader data lifecycle management strategy — alongside existing tape, disk, and cloud tiers.
If you are planning long-term storage infrastructure, managing large archival datasets, or simply want to understand how this technology might affect your data strategy, we are happy to have that conversation now.
