CD Duplication & Replication – Understanding The Red Book Standards
One of the core factors about CD duplication & replication you would encounter too often is master. Under this you would come across a term Red Book and its standard. Red Book standards are defined as minimum requirements a CD (compact disk) should possess and holds great importance for CD replication and duplication.
More explicitly, they are the technical aspect which the CD manufactures require to follow. For consumers if you are asked to use a CD with Red Book specification would only mean that you need to buy CDs which are following these standards. Red Book standards become very important, if you have a CD replication or CD duplication to be done and you need to prepare a master.

1) 79.8 minutes is the maximum playing time for a Red Book CD.
2) 4 seconds is the duration for each track with 2 minutes pause included.
3) 99 are the maximum tracks available.
4) International Standard Recording Code (ISRC) is important and should be included.
5) “Single Speed” or transfer rate or 1X should be 150 kilobytes per second
6) Sample rate of 44.1 KHz, or 44,100 samples per second.
Technical Aspect – CD Replication/Duplication
When a Red Book disc is taken and checked for technical aspects you’ll find that it will have;
Lead In – for a CD session is its starting point. TOC i.e. Table of content and the address for the next session is also contained in the Lead -in. Here the TOI is important as it stores the layout of the tracks on the disc.
Lead Out -Lead-Out – or the ending part of the CD, is rewritten when the session is closed Other terms of Red Book Standard include tracks, programs and sessions
Other Addition – CD Replication and CD Duplication With time there have been significant changes for the Red Book format. We now have the Blue, Yellow, Orange, White and Green Book formats. Out of which the Blue Book Format is most significant. It is also known by CD Plus or ECD”, “Enhanced CD” and “Enhanced CD-ROM,” and comes handy as it allows both audio and data to be included into one CD.
Non Standard Disks – Can Be Used For CD Replication/ CD Duplication
Business Card CD – is fast becoming a great replacement for the business cards and making multi-media presentations. The big difference lies in the amount of information they can store, which is a whopping 30-40 megabytes and ease of use.
Hockey Rink CD – Come with a capacity of 50 – 80 megabytes and are optimal for multi-media presentations, demo tracks, software demos, trade show giveaways etc. It is slightly different from mini-CDs as it’s shaped differently and the disk space is also less.
Mini CD’s – derives its being from standard CD and can hold 150 to 210 megabytes of data, approximately 18 to 24 minutes of data.
