According to one standard, a multiple session audio disc has only two sessions, namely an audio session including successive audio tracks, and a following data session including just one data track. It has been determined that where copying of such a disc is to be undertaken using several common Microsoft Windows operating systems, the disc can be copy protected by breaching the rules of this standard. Specifically, if a two session audio disc is provided which has two tracks in the second data session, the Windows NT, Windows 2000 and Windows XP operating systems will fail to reconcile the data on the disc. As the operating systems are prevented from copying the audio information on the disc the use of the non-standard format acts to copy protect the optical disc.
