Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

CLAIMS:

1. A method for optical disc writing, comprising steps:
Acquiring writing history information of the optical disc, wherein the data storage area of the optical disc is divided into several writing areas by a starting address and an ending address of each writing in the history information;
Selecting one writing area from the plurality of writing areas for the current writing for the optical disc;
Determining write strategy of the optical disc adopted by the current writing for writing the optical disc; and
Updating the writing history information of the optical disc.

2. The method according to claim 1, further comprising steps: according to the writing history information of the optical disc, counting the writing times that each divided area has been subjected to.

3. The method according to claim 2, wherein the step of selecting comprises selecting based on the counted writing times for each area of the optical disc.

4. The method according to claim 3, wherein the step of selecting further comprises selecting based on the storage space needed by data of the current writing for the optical disc.

5. The method according to claim 1, wherein the writing history information further comprises write strategy for the optical disc adopted by each optical disc writing.

6. The method according to claim 1 or 5, wherein the write strategy for the optical disc is determined according to the write strategy for the optical disc in the writing history information of the optical disc.

7. The method according to claim 6, wherein the write strategy for the optical disc is determined according to the write strategy for the optical disc for the same writing times in the writing history information of the optical disc.

8. The method according to claim 1 or 5, wherein the updating comprises adding the information of the current writing for the optical disc to the writing history information of the optical disc.

9. The method according to claim 8, wherein the information of the current writing for the optical disc comprises the starting address and ending address of the current writing.

10. The method according to claim 9, wherein the information of the current writing for the optical disc further comprises the write strategy for the optical disc adopted by the current writing.

11. An optical disc writing apparatus, comprising:
An acquiring means, for acquiring writing history information of the optical disc, wherein the data storage area of the optical disc is divided into several writing areas by the starting address and ending address of each writing in the history information;
A selecting means, for selecting one writing area from the plurality of writing areas for the current writing of the optical disc;
A determine means, for determining write strategy of the optical disc adopted by the current writing for writing the optical disc; and
An update means, for updating the writing history information of the optical disc.

12. The optical disc writing apparatus according to claim 11, further comprising: A counting means, according to the writing history information of the optical disc, for counting the writing times of the optical disc that each divided area has been subjected to.

13. The optical disc writing apparatus according to claim 12, wherein the selecting comprises selecting based on the counted writing times for each area of the optical disc.

14. The optical disc writing apparatus according to claim 13, wherein the selecting comprises selecting based on the storage space needed by data of the current writing for the optical disc.

15. The optical disc writing apparatus according to claim 11, wherein the writing history information further comprises the write strategy of the optical disc adopted by each optical disc writing.

16. The optical disc writing apparatus according to claim 11 or 15, wherein the write strategy of the optical disc is determined according to the write strategy of the optical disc in the writing history information of the optical disc.

17. The optical disc writing apparatus according to claim 16, wherein the write strategy of the optical disc is determined according to the write strategy for the optical disc for the same writing times in the writing history information of the optical disc.

18. The optical disc writing apparatus of claim 11 or 15, wherein the updating comprises adding the information of the current writing for the optical disc to the writing history information of the optical disc.

19. The optical disc writing apparatus according to claim 18, wherein the information of the current optical disc writing comprises the starting address and ending address of the current writing.

20. The optical disc writing apparatus according to claim 19, wherein the current optical disc writing information further comprises the optical disc write strategy adopted by the current writing.
