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.

Claims

1. A record carrier having a track, comprising:

a first information volume recorded in the track in a first area, the first information volume including audio information in a first program area of the first area, and a first lead-out signal in a first lead-out area at the end of the first area, the first lead-out signal denoting the end of the first information volume; and

an additional information volume recorded in the track in an additional area after the first area, the additional information volume including additional non-audio information related to the audio information included in the first program area in an additional program area of the additional area, and an additional lead-out signal in an additional lead-out area at the end of the additional area, the additional lead-out signal denoting the end of the additional information volume;

wherein the additional information volume further includes pointer information which enables audio information included in the first program area to be located on the basis of information identifying one or more locations in the first program area where one or more portions of the audio information included in the first program area are located.

2. The record carrier as claimed in claim 1, wherein the additional information volume further includes a control file in a control area of the additional area which is separate from the additional lead-out area, the control file including control information for use in searching for audio information included in the first program area.

3. The record carrier as claimed in claim 2, wherein the first information volume further includes a table of contents indicating addresses within the first program area of predetermined parts of the audio information included in the first program area, the table of contents being included in lead-in area of the first area preceding the first program area.

4. The record carrier as claimed in claim 2, wherein the audio information in the first program area is formatted in accordance with the Compact Disc Digital Audio standard.

5. The record carrier as claimed in claim 4, wherein the additional non-audio information in the additional program area is formatted in accordance with the CD-ROM standard.

6. The record carrier as claimed in claim 1, wherein the first information volume further includes a table of contents indicating addresses within the first program area of predetermined parts of the audio information included in the first program area, the table of contents being included in lead-in area of the first area preceding the first program area.

7. The record carrier as claimed in claim 6, wherein the audio information in the first program area is formatted in accordance with the Compact Disc Digital Audio standard.

8. The record carrier as claimed in claim 7, wherein the additional non-audio information in the additional program area is formatted in accordance with the CD-ROM standard.

9. The record carrier as claimed in claim 7, wherein the table of contents is formatted in accordance with the Compact Disc Digital Audio standard.

10. The record carrier as claimed in claim 6, wherein the table of contents is formatted in accordance with the Compact Disc Digital Audio standard.

11. The record carrier as claimed in claim 1, wherein the audio information in the first program area is formatted in accordance with the Compact Disc Digital Audio standard.

12. The record carrier as claimed in claim 11, wherein the additional non-audio information in the additional program area is formatted in accordance with the CD-ROM standard.

13. The record carrier as claimed in claim 1, wherein the additional non-audio information in the additional program area is formatted in accordance with the CD-ROM standard.

14. The record carrier as claimed in claim 1, wherein the pointer information is included in the additional program area.

15. The record carrier as claimed in claim 1, wherein the additional area further includes a lead-in area at the beginning of the additional area, the lead-in area being located after the first lead-out area and before the additional program area;

and the pointer information is included in the additional program area.

16. The record carrier as claimed in claim 15, wherein the pointer information includes one or more references identifying one or more locations in the first program area where one or more portions of the audio information included in the first program area are located.

17. The record carrier as claimed in claim 1, wherein the pointer information includes one or more references identifying one or more locations in the first program area where one or more portions of the audio information included in the first program area are located.

18. The record carrier as claimed in claim 1, wherein the first area further includes a first lead-in area at the beginning of the first area, the first lead-in area being located before the first program area;

and the additional area further includes an additional lead-in area at the beginning of the additional area, the additional lead-in area being located after the first lead-out area and before the additional program area.

19. The record carrier as claimed in claim 2, wherein the control information includes reference information which references the pointer information.
