Bronzing is due to a fault in the manufacturing process and can therefore neither be prevented nor be stopped once it has begun. However, storage conditions certainly seem to contribute to the speed of the decay, as some bronzed CDs were already reported as unreadable in the mid-1990s, whereas others were still playable as recently as 2012. As it was noted that CDs stored in p
The ReWritable Audio CD is designed to be used in a consumer audio CD recorder, which will not (without modification) accept standard CD-RW discs.

Each company released separate versions of this recorder, with Ottens responsible for the Philips version. [6] Ottens was confronted with many technical problems very early after the release of the product. Within a few months of the products release, a majority of devices were returned to Philips for repair.
Disc rot is the tendency of CD, DVD, or other optical discs to become unreadable because of chemical deterioration. The causes include oxidation of the reflective layer, reactions with contaminants, ultra-violet light damage, and de-bonding of the adhesive used to adhere the layers of the disc together.
A CD drive can have extraction errors when the data on the disc is not readable due to scratches or smudges. The drive can compensate by supplying a "best guess" of what the missing data was, then supplying the missing data.
