Abstract
A record carrier on which a first information volume and an additional information volume are recorded. The first information volume includes audio information, preferably recorded in accordance with the Compact Disc Digital Audio standard. The additional volume includes additional non-audio information related to the audio information recorded in the first information volume. The additional volume also includes control information for searching for information in both the first and the second information volumes. A dedicated data reading apparatus for such a record carrier firstly accesses the additional information volume. On the basis of the control information, the dedicate data reading apparatus can also access the audio information in the first information volume. An audio reading apparatus which can not handle the additional non-audio information automatically accesses the first information volume.
