Abstract
A system and method for producing and using a protected optical media is described. One feature provides for a compact disc containing digital rights management protection to prevent unauthorized copying of copyrighted materials. Another feature provides for secure copying, storage, transfer, and playback of digital audio content from a protected compact disc or computer storage. Yet another feature provides for a versatile optical media that can be used in both traditional audio compact disc players and in computer CD-ROM drives without risking the security of the content on the media or preventing purchasers from having a robust content experience.
