MediaRange BD-R Blu-ray Disc 25GB 6x, Single Layer, 25-Pack Cakebox Spindle, Full-Surface Inkjet Printable

MediaRange MR512 is a pack of 25 BD-R Blu-ray discs with 25 GB per disc (single layer), rated for up to 6x writing and supplied in a cakebox spindle — aimed at archives and deliveries you want to label professionally with your own printed artwork.

As write-once media, once a session is finalised the data cannot be erased or overwritten — exactly what you want for archives, legal and accounting records, finished projects and handover copies. The top is white full-surface inkjet-printable with a print area of Ø 23–118 mm, so you can print titles, logos or artwork directly onto the disc with a compatible inkjet printer.

• 25 × MediaRange BD-R discs, 25 GB each (625 GB total)
• A clear-lid cakebox with the discs stacked on the centre post — no individual sleeves or cases
• Blank discs with the white full-surface 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. MediaRange quotes up to 135 minutes of Full HD video per disc.
• Rated 6x (216 Mbps). Actual speed depends on your writer and burning software; for archive copies a moderate speed with verification after burning is a sensible habit.
• Write-once: the disc cannot be wiped by mistake or by ransomware once written, a real advantage for offline archive copies.
• Print area Ø 23–118 mm: you need an inkjet printer with a CD/DVD/Blu-ray print tray; let the ink dry fully before stacking or burning.
• MediaRange uses an HTL recording layer described as UV- and scratch-resistant and designed for long archival life; it recommends storage at about 23 °C and 50% relative humidity, away from sunlight.
• A cakebox 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.
• Write-once means no erasing: if you need to reuse discs, choose BD-RE instead.
• 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.
