ACU-DISC Blu-Ray BD-R DL Discs combine a 50 GB dual-layer format with a thermal white surface and inorganic dye for longer-lasting storage. Are these discs the sensible choice for routine backups and media archiving?
⚡ At a Glance
- • Storage Capacity: Dual-layer 50 GB per disc, suitable for large backups and HD video
- • Best for: Home archivists and small businesses needing reliable writable Blu-ray media
- • Not ideal for: Users who require rewritable discs or very high-speed recording
Each disc stores 50 GB using a dual-layer BD-R DL format. Inorganic dye and a thermal white surface help with longevity and easy labelling.
Long-lasting archives – Thanks to inorganic dye
Inorganic dye formulation resists degradation over time more effectively than many organic dye formulations, stabilising the recorded layer. A more stable dye reduces the risk of data loss from media decay.
Longer retention of recorded data gives confidence for archival use, so jobs do not need frequent re-backing up.
Large single-disc backups – With 50 GB dual-layer capacity
Dual-layer BD-R DL architecture holds two data layers on one side of the disc, effectively doubling single-layer capacity to 50 GB per disc. The 4x write rating supports standard Blu-ray burning speeds.
Fewer discs are required for video projects and large archives, simplifying storage and retrieval of large files.
Clear, durable labelling – With thermal white surface
Thermal white surface accepts marker pens and is designed for thermal printing, producing legible, fade-resistant labels. The printable layer adheres cleanly without affecting the recording layer.
Simple, permanent labelling keeps archives organised and easy to identify at a glance.
