CMC offers Diamond CD-R, which is recommended if you are looking for a recordable CD-R with no color on the record side. A Diamond CD-R is pure silver, so the bottom looks very similar to the top side. These discs are also called Platinum CD-Rs. CMC’s Diamond CD-R is the product that looks the most like a replicated, store bought CD. Like standard CD-R media, Diamond CD-R is write-once, which means it can be fully recorded once and played repeatedly. Please inquire for complete specs and the latest compatibility list.
