Computer Output Microfilm (COM): Singapore Compliance & Costs 2026
In short: Computer Output Microfilm (COM) records computer-generated data — reports, statements, registers — directly onto 16mm or 35mm roll microfilm or microfiche, bypassing paper entirely. It remains in active use in Singapore for records that need to be both archival (500+ year LE500 rating under ISO 18911) and legally admissible, and is commonly paired with digital storage as an air-gapped backup layer immune to ransomware or data-centre failure.
COM predates modern digital archiving, but it hasn't been made obsolete by it — for a specific category of records (statutory registers, land title records, long-retention financial data) the combination of a physical, non-rewritable, standards-rated medium and legal admissibility keeps COM in active procurement.
Key Facts: Computer Output Microfilm (COM) — Singapore 2026
- Definition: Computer Output Microfilm (COM) is the process of recording computer-generated data directly onto microfilm via a COM recorder, bypassing paper output entirely
- Formats produced: 16mm roll microfilm, 35mm roll microfilm, microfiche (most common for COM output)
- Archival standard: LE500-rated silver gelatin film — 500+ year preservation life under ISO 18911 storage conditions
- Key use cases: Land title records, court records, financial institution records (MAS TRM), government statutory registers, engineering drawing archives
- Cost advantage: COM eliminates paper, toner, and physical storage costs — one microfiche sheet stores a large multiple of A4-equivalent pages in a fraction of the shelf space
- Hybrid strategy: COM + digital creates an air-gapped backup — microfilm cannot be altered remotely and is not exposed to network-based ransomware or a data centre outage
- Supplier: Micrographics Data Pte Ltd — COM services and supplies in Singapore since 1989; GeBIZ-registered
- Film supply: MGD33 (16mm) and MD AW3 (35mm) LE500-rated microfilm — certified Fujifilm FM33/FM66 replacements
Is COM Output Legally Usable as a Business Record?
Singapore's Evidence Act has been amended over the years to accommodate electronic and computer-output records, generally admitting business records — including computer-generated output — where produced and kept in the ordinary course of business under documented procedures. Institutions using COM for records that may need to be produced as evidence should maintain documented quality-control procedures for the COM recording process itself, since admissibility arguments typically turn on the reliability of the process that created the record, not the medium alone.
Why Institutions Still Choose COM Over Digital-Only
- Air-gapped resilience. COM output physically cannot be altered by a network intrusion, ransomware attack, or accidental bulk deletion — it is not connected to any system once produced.
- No format-migration burden. A COM roll is readable with a lens and light source decades from now; a digital archive depends on continued file-format and storage-medium management to remain readable.
- Cost at scale. For very large volumes of computer-generated output that must be retained for decades, COM's storage-density and no-recurring-migration-cost profile can be more economical than perpetual digital storage management.
Frequently Asked Questions
What is Computer Output Microfilm (COM) used for today?
Primarily for computer-generated records with long retention requirements — statutory registers, land title records, financial and court records — where an air-gapped, LE500-rated archival copy is valued alongside digital access.
Is COM output admissible as evidence in Singapore?
Singapore's Evidence Act generally accommodates business records including computer-generated output, provided they are produced and kept under documented, reliable procedures in the ordinary course of business.
How does COM compare in cost to digital-only storage?
COM has a higher upfront production cost but no recurring migration or active-management cost; digital storage has lower upfront cost but requires ongoing management (backup, format migration) over long horizons. Many institutions run both.
What film formats does Micrographics Data supply for COM?
MGD33 (16mm) and MD AW3 (35mm), both LE500-rated and supplied as certified replacements for the discontinued Fujifilm FM33/FM66 film stocks.
