Stellar Data Recovery has introduced Stellar Phoenix CD DVD Data Recovery for Mac (http://macte.ch/OfpnG). It requires Mac OS X 10.4 or higher and costs US$39.

Featuring an interactive user interface, CD DVD Data Recovery for Mac is a tool that can recover data from all types of optical media such as CD, DVD, Blu-ray Disc, and HD DVD. It’s designed specifically to recover and restore lost or inaccessible data from physically damaged or incorrectly burnt optical media.

The software mounts the optical media and then scans the entire disc for safely restoring every piece of lost, deleted, or fragmented data. A demo version is that allows you to preview all the recoverable files before actual recovery.
