12. The recording medium of claim 11, wherein the status indicates whether the associated continuous recording area is a start of a group of continuous recording areas.

13. The recording medium of claim 1, wherein if the recording mode is determined to be the random recording mode, the type of the second information is a space bit map indicating recordation status of a data area of the recording medium.

14. The recording medium of claim 13, wherein the space bit map includes space bit map data, a data pointer pointing to the space bit map data, and a length indicator indicating a length of the space bit map data.

15. The recording medium of claim 14, wherein the data pointer indicates a first physical sector number of the space bit map data.

16. The recording medium of claim 14, wherein the space bit map data includes a status indicator associated with each recording unit of the data area, the status indicator indicating whether data is recorded in the associated recording unit.

17. The recording medium of claim 16, wherein the recording unit is a cluster.

18. The recording medium of claim 14, wherein the space bit map further includes a format indicator indicating a format of the space bit map.

19. The recording medium of claim 14, wherein

the recording medium is a dual layer optical disc;

and

the space bit map further includes a layer indicator indicating a layer to which the space bit map corresponds.

20. A method of initializing a recording medium, comprising:

determining a recording mode for the recording medium, the recording mode being one of a sequential recording mode and a random recording mode;

determining use status information based on the determined recording mode; and

recording an indicator of the determined recording mode in a management area of the recording medium,

wherein the determined use status information is updated in the management area until the recording medium is finalized.

21. The method of claim 20, further comprising:

recording sequential recording information as the use status information in the management area if the recorded recording mode indicator indicates the sequential recording mode, the sequential recording information providing information on continuous recording areas in a data area of the recording medium.

22. The method of claim 20, further comprising:

recording a space bit map as the use status information in the management area if the recorded recording mode indicator indicates the random recording mode, the space bit map provides information on a recordation status of a data area of the recording medium if the recorded recording mode indicator indicates a random recording mode.

23. A method of recording management information on a recording medium, comprising:

reproducing a recording mode indicator from a management area of the recording medium;

judging a recording mode of the recording medium based on the recording mode indicator; and

recording use status information for the recording medium in the temporary defect management area based on the judging step, the use status information providing information on use of a data area of the recording medium to store data;
