Abstract

The present invention provides a data structure recorded in a recording medium, data recording method and data recording apparatus, in which data are recorded in a high-density recording medium such as a Blu-ray disc. In recording data per cluster within a recording medium, a data structure recorded in the recording system is characterized in that the data includes an address unit in which a plurality of per recording unit address fields included in a corresponding cluster and a control information field indicating per recording unit attribute are recorded and in that each information configuring the control information field is identified by byte unit.

wherein if the data-recording block unit is recorded by substitution of the previous original data-recording block unit, the second address information includes a first physical sector number of the previous original data-recording block unit, and wherein if the second address information is set to zero, the data-recording block unit is not a substitution for the previous original data-recording block unit.

2. The storage medium of claim 1, wherein the status information is provided by allocating 2 bits to per sub-data-recording block unit.

3. The storage medium of claim 2, wherein at least four sequential bytes within the control information configure the status information for all sub-data-recording block units within the corresponding data-recording block unit.

4. The storage medium of claim 1, wherein at least four sequential bytes within the control information configure the second address information.

5. The storage medium of claim 1, wherein the control information includes recording data information indicating when the corresponding data-recording block unit is recorded.

6. The storage medium of claim 5, wherein at least two sequential bytes within the control information configure the recording data information.

7. The storage medium of claim 1, wherein the control information includes unique identification information of a recorder having recorded the corresponding data-recording block unit.

8. The storage medium of claim 7, wherein at least two sequential bytes within the control information configure the unique identification information of the recorder.

9. The storage medium of claim 1, wherein the address unit further includes parity information for error correction.

10. A method of recording data in a user data area and a spare area of a recording medium using a computer having a microprocessor, comprising the steps of:

generating a data structure including data to be recorded by data-recording block unit, wherein the data which are stored in at least one of the user data area and the spare area, includes an address unit, the address unit including a plurality of address fields and control information, each address field indicating an address of a corresponding sub-data-recording block unit within the data-recording block unit, the control information including status information and second address information, the status information indicating the status of the stored data contained in each individual sub-data-recording block unit included in the data-recording block unit, the second address information indicating an address of a previous original data-recording block unit, and

recording the generated data structure in the recording medium, wherein if the data-recording block unit is recorded by substitution of the previous original data-recording block unit, the second address information includes a first physical sector number of the previous original data-recording block unit, and wherein if the second address information is set to zero, the data-recording block unit is not a substitution for the previous original data-recording block unit.

11. The method of claim 10, wherein the status information is provided by allocating 2 bits to per sub-data-recording block unit.

12. The method of claim 11, wherein at least four sequential bytes within the control information configure the status information for all sub-data-recording block units within the corresponding data-recording block unit.

13. The method of claim 10, wherein at least four sequential bytes within the control information configure the second address information.

14. The method of claim 10, wherein the control information includes recording data information indicating when the corresponding data-recording block unit is recorded.

15. The method of claim 14, wherein at least two sequential bytes within the control information configure the recording data information.

16. The method of claim 10, wherein the control information includes unique identification information of a recorder having recorded the corresponding data-recording block unit.

17. The method of claim 16, wherein at least two sequential bytes within the control information configure the unique identification information of the recorder.

18. The method of claim 10, wherein the address unit further includes parity information for error correction.

19. An apparatus for recording data in a user data area and a spare area of a recording medium, comprising:
