Why is DDP better than a CD Pre-Master?
DDP (Data Description Protocol) is the professional way to master for CD duplication.
Most manufacturers agree that DDP is a fully error corrected and ultra-reliable
transfer format. CDR Masters have potential problems. CDRs contain errors, caused
by imperfections on the surface through fingerprints, dust and manufacturing
tolerances. Also, some brands of CDR, may contain ten times the average number
of errors of a pressed CD. Delivering a DDP, that has lower error rates than
CDR, eliminates mistakes at the manufacturing plant. Only DDP master tapes provide
a verifiable data transfer from the hard drive to the final CD and employ sophisticated
error-checking. Our DDP masters are fully error-checked and allow for a full
data check before a glass master is produced. A DDP is your best guarantee that
your master will be transferred and your CD manufactured with no problems at
If however, the plant of your choice will only accept CDR Masters, we'll be happy to supply you with a fully-verified CDR / gold disc production master.
With our DDP & CDR/gold disc Masters it is possible to add a bar code number
and International Standard Recording Codes (ISRC) for each track which are embedded
into the data on an audio CD to identify the owner of each track. Used extensively
for royalty payments, ISRCs consist of a series of numbers which are allocated
by the BPI in the UK, and regulated worldwide by the IFPI.
