<p>Compact disk readers first read the index of the content of a compact disk introduced to be read and record it in total or in part. In spite of the high degree of redundancy of such indexes, it may happen that they are unreadable for compact disk readers. To allow a compact disk reader to work in spite of the unreadability of the index, the scanning device of the compact disk reader looks for the end of the index. The part of the compact disk which follows the index can then be reproduced. The index data are recovered during reproduction of the compact disk or during a previous stage by stage scanning.</p> |
