8. A method according to claim 4, wherein said coexistence flag is a file itself.

9. A method according to claim 4, wherein said coexistence flag is a flag recorded in the file.

10. A reproducing device for indicating data recorded on a recording medium, comprising:

means for obtaining the data from said recording medium on which said data has been recorded, in which said data includes a first data group and a second data group, said first data group is recorded onto said recording medium in accordance with a first recording format, said second data group is recorded onto said recording medium in accordance with a second recording format different from said first recording format, said first recording data group includes first list indication data which is used for a first list indicating method, said second recording data group includes second list indication data which is used for a second list indicating method different from said first list indicating method, said first list indication data indicates said first data group, and said second list indication data indicates said second data group; and

means for list-indicating said first data group and said second data group.

11. A device according to claim 10, wherein said first data group and said second data group are list-indicated by said first list indicating method.

12. A device according to claim 10, wherein said first data group and said second data group are list-indicated by a list indicating method which is different from said first list indicating method and is different from said second list indicating method.

13. A device according to claim 10, wherein if there is a coexistence flag which permits said first data group and said second data group to be list-indicated, said first data group and said second data group are list-indicated.

14. A device according to claim 10, wherein said first data group has a BDMV format and said second data group has a BDAV format.

15. A device according to claim 11, wherein said first data group has a BDMV format and said second data group has a BDAV format.

16. A device according to claim 11, wherein said first data group has a BDAV format and said second data group has a BDMV format.

17. A device according to claim 13, wherein said coexistence flag is a file itself.

18. A device according to claim 13, wherein said coexistence flag is a flag recorded in the file.

19. A recording device for recording data onto a recording medium, wherein

when a first data group of a data format according to a first recording format and a second data group of a data format according to a second recording format different from said first recording format are recorded, they are recorded so that said first recording data group includes first list indication data for a first list indicating method and said second recording data group includes second list indication data for a second list indicating method different from said first list indicating method.

22. A device according to claim 19, wherein said first data group has a BDMV format and said second data group has a BDAV format.

23. A device according to claim 19, wherein said first data group has a BDAV format and said second data group has a BDMV format.
