FAQ - CD/DVD Duplication

Click on a question to expand the answer

What do all of the disc abbreviations stand for?

  • CD is a Compact Disc, -R is the recordable version.
  • DVD is a Digital Video Disc, -R & +R are the recordable versions.
  • BD is a Blu-Ray Disc, -R is the recordable version.
  • RW refers to re-writable, meaning that the data can be erased and rewritten many times. (-R discs can only be written to once.)
  • +R or -R are basically the same disc except +R discs use a different system for tracking and speed control. We support the duplication of both types.

The chart below shows capacity and details for the most popular types of media used in disc duplication:

Disc Type:




700 Megabytes

Used for audio, data, and typically video only meant for computer playback.

CD-R Minidisc

180 Megabytes

A smaller version of the CD-R that will fit in your pocket.

CD-R Business Card

50 Megabytes

The smallest version of a CD-R and is shaped like a business card. Great for marketing handouts. Media is playable in tray-loading drives only.

DVD-R / +R

4.7 Gigabytes

Used for video, data, and other multimedia files. Used on TV set-top box players and computer systems.

DVD Dual Layer

8.4 Gigabytes

Used for video, data, and other multimedia files. Used on TV set-top box players and computer systems. Functions the same as a single-layer DVD while holding nearly twice the amount of data.


25 Gigabytes

Blu-Ray is the same physical size as a DVD at 120mm in diameter and 1.2mm thick. This media uses a blue laser rather than a red one and provides a much higher recording density. This allows for the use of fewer discs for data applications as well as duplication of HD Digital recordings. A BD-R cannot use the copy protection AACS (Advanced Access Content System) that is found on replicated discs. The 25GB version can hold approximately 2-4 hours of HD video. A Blu-Ray drive is required to read Blu-Ray discs. The same drives are also compatible with DVD and CD discs.

BD-R Dual Layer

50 Gigabytes

This version holds twice as much data as the 25GB single-layer BD-R discs.

How do I prepare my master discs for duplication?

  • Choose the appropriate blank media to meet the needs of your project's size and functionality, ie: CD, DVD, or Blu-Ray.
  • Make sure that the disc is free of scratches or debris, before and after burning
  • Use well known copy / burning application software for best results (ie: Roxio or Nero).
  • Test your master disc thoroughly to insure that it functions properly for your needs. Duplicates will be exact copies of the master that you provide.
  • Always keep 1 copy of your master for your records.
  • Protect your master in a sleeve or jewel case when transporting.
  • Send your master to: Diversified Systems Group, Inc. 8700 148th Ave NE, Redmond, WA 98052

Here are a few things to be aware of while producing masters for the following projects:

Data CD's and DVD's

  • Avoid using packet writing utilities such as "Direct CD" and "Drag N Drop". These utilities produce masters that are NOT suitable for duplication or replication.

Audio CD's

  • Burn all audio tracks on 1 session. Choose options to close or finalize your disc if given the option.

Video DVD's

  • Using your burning software, choose to create a Video DVD project.
  • After burning the project, explore the disc on your computer's system browser to check for the presence of Audio_TS and Video_TS folders. These folders indicate that your disc has the proper format for maximum compatibility.
  • Do not leave Video DVD's appendable. Make sure to close or finalize the session so data cannot be added later.

What is NTSC and PAL? Do you provide a conversion service?

NTSC, named for the National Television System Committee, is the analog television system that is used in most of North America. PAL, short for Phase Alternating Line, is an analog television color encoding system used in broadcast television systems in many countries outside of North America. We can convert your NTSC Video DVD to play properly on PAL television systems, and convert PAL to NTSC, as well.
