Agold compact disc is one in which gold is utilized in place of the high-purity aluminiumorsilver commonly used as the reflective coating on ordinary CDs and CD-Rs respectively. Gold disks are available as both CDs and CD-Rs as well, and are compatable with standard players and recorders.
The advantage of the gold reflection layer lies in its significant resistance to corrosion compared to the aluminium layer found on ordinary compact discs. As such, gold CDs were seen as a potential solution to the incidence of CD rot on early CDs (mainly manufactured by PDO UK).[1]
In 2014, Audio Fidelity, an American publisher of audiophile CDs, announced that it was abandoning the gold format and moving to the hybrid Super Audio CD (SACD) format for future releases. [2]
Since 2016, the Australian division of Sony Music have been reissuing back catalogue CDs as budget-priced (under $10) issues with gold CDs under the "Gold Series" branding.
