Verbatim M-DISC BD-R Blu-ray Disc 25GB 4x, Archival, 10-Pack Spindle, Inkjet Printable

Verbatim 43825 is a pack of 10 M-DISC BD-R Blu-ray discs with 25 GB per disc (single layer), rated for up to 4x writing and supplied in a spindle — aimed at long-term archiving of documents, photos and records that must stay readable for years.

M-DISC is Verbatim's archival format: instead of the dye used in conventional recordable discs, the data is written into a rock-like inorganic layer that Verbatim designs to resist light, temperature and humidity. The top is inkjet-printable with a print area of Ø 40–118 mm, so you can print titles, logos or artwork directly onto the disc with a compatible inkjet printer.

• 10 × Verbatim M-DISC BD-R discs, 25 GB each (250 GB total)
• A spindle tub with the discs stacked on the centre post — no individual sleeves or cases
• Blank discs with the inkjet-printable surface ready for your own artwork — no printer, ink or labelling software included

• 25 GB per disc is about five times a single-layer DVD — enough for a large photo library, a full system image of a small PC or a long Full HD recording.
• Rated 4x (144 Mbps). Actual speed depends on your writer and burning software; for archive copies a moderate speed with verification after burning is a sensible habit.
• Archival focus: Verbatim positions M-DISC for data that must survive decades; it is still good practice to keep a second copy in a different location.
• Print area Ø 40–118 mm: you need an inkjet printer with a CD/DVD/Blu-ray print tray; let the ink dry fully before stacking or burning.
• Inkjet-printable top (Ø 40–118 mm) so each archive disc can carry its own title and date.
• A spindle is the most economical way to buy discs in quantity; if you hand discs to clients or store them long-term, budget for separate jewel or slim cases.
• Windows and macOS can write simple data discs from the file manager; for verification after burning, multi-session control or Blu-ray video authoring, use dedicated burning software.
• For important archives burn two copies on separate discs and keep them in different locations — one disc is a copy, two discs in two places are a backup.

• CD or DVD-only drives cannot read or write these discs — you need a Blu-ray writer to burn them and a Blu-ray drive or player to read them.
• A standard BD-R writer without M-DISC Ready support is not supported for burning these discs.
• Laser printers, thermal disc printers and adhesive labels are not the intended method — this surface is for inkjet disc printing.
• Most current laptops and all current Macs have no optical drive; you will need an external USB Blu-ray writer.
• A data disc is not automatically a playable movie: to play in a Blu-ray player, video must be authored as a Blu-ray video disc with suitable software.
