Specifications for DVD-ROM data master discs

Check your content

We do not check your data discs before duplicating. It is your responsibility to check whether the content of your discs works well on a variety of players, and on a variety of different computers and operating systems.

  • If you have images in a presentation, such as a PowerPoint file, make sure that the images are embedded in the file, not just linked to a file on your local system.
  • Use standard system fonts. If you use an unusual font, check to see what happens if you play your discs in a computer that doesn't have the font you've used.
  • If you're making your disc playable on Windows and Macintosh computers, make sure that it works both on Mac OS9 and MacOSX.
  • For very high compatibility, keep file names to the old MS-DOS naming system of eight characters plus a three letter extension.
  • If you must use long filenames, keep names to less than 31 characters to ensure compatibility with MacOS9 and earlier. Even if you are not concerned about compatibility with Macintosh computers, keep file names shorter than 64 characters to ensure compatibility with older versions of Windows operating system.
  • Use only alpha-numeric characters in the file names. The underscore (_) and hyphen (-) are also acceptable.
  • Avoid other characters. The slash symbol (/) popularly used in Macintosh file names is incompatible with MS-DOS and Windows operating systems. The other Macintosh habit of putting spaces at the beginning or end of file names is also incompatible with MS-DOS and Windows.
  • For multimedia content, avoid less popular playback formats unless you're sure that your recipients can play them.

Do not use Packet-Writing

Packet-written CDs, such as those written by Adaptec's Direct-CD and Nero's InCD, are NOT suitable for duplication. If you supply a packet-written disc, it will always need to be remastered. Additional charges may apply and additional turnaround time will needed.

Alternative data formats

If you are unable to supply a data CD or DVD master, you can also supply data in the following ways (Additional charges may apply, and you will need to allow extra time.)

In order for us to complete your duplication job accurately, unless you supply us with a ready-to-duplicate disc, you must check the master disc before we proceed.

Alternative ways of supplying data to us include:

  • FTP
  • DropBox
  • Email
  • USB drive
  • SD Card
