CD Duplication speeds

All CD Duplicator and DVD Duplicator speeds are calculated on the original audio CD which held 74 minutes of audio and 650MB of data.

From the table above you can see from 48x - 52x the time difference taken to write a complete disc is only 7 seconds. Therefore any speeds above 48x become largely academic in terms of time savings. The only alternative to increase CD Duplicator throughput is to buy a machine with multiple CD writers.

When buying CD media always make a note of the CD writing speed. Otherwise if you purchase 16x CD media for use in your CD Duplicator with 48x CD writers the CD Duplicator will only write at 16x.

Many CD Duplicators also display the writing speed, which 9 times out of 10 when writing a new disc never displays the quoted CD Duplicator speed, this is because a CD or DVD disc is written from the centre out, in one continuous spiral. In the middle of the disk the speed might be 1x, but as the disc fills with data the "x" speed also increases.  This is known a CAV or Constant Angular Velocity. So if you only ever write 100MB of data using your 52x CD Duplicator you will probably only ever see the machine reach 32x.

Please see below a table of the speed "x" and time taken to write a complete 650MB disc.
