11. The method of claim 1, further comprising recording additional audio group information, in the second region, for grouping and managing the plurality of additional audio data, the additional audio group information including second virtual deletion information for virtually deleting the additional audio parts, the second virtual deletion information for the additional audio part corresponding to a still picture whose corresponding virtual deletion information is in the virtual delete state is set to the virtual delete state, and the additional audio part set to the virtual delete state is not to be reproduced.
12. The method of claim 11, wherein if the virtual delete state of the second virtual deletion information is cleared, the corresponding additional audio part is restored to be reproducible.
13. The method of claim 11, wherein if all additional audio parts of a same additional audio group in the additional audio group information are in the virtual delete state, all data of the corresponding additional audio group and the corresponding additional audio group information are deleted from the recording medium.
14. The method of claim 1, wherein each of the first, second and third regions exists in separate files.
15. The method of claim 1, wherein the first and third regions exist in one file.
16. The method of claim 1, wherein the still picture group information of the second region further includes still picture group general information containing information relating to a number of the still picture groups, and additional audio general information containing information relating to a number of the additional audio groups.
