Abstract

A method of one embodiment of the invention is disclosed that optically reads a marking on a label region of an optical disc, to determine access to information stored on a data region of the optical disc. Access to the information stored on the data region of the optical disc is then permitted based on the marking on the label region of the optical disc that has been optically read.

Claims

1. A method comprising:

optically reading a marking on a label region of an optical disc to determine access to information stored on a data region of the optical disc; and

,

permitting access to the information stored on the data region of the optical disc based on the marking optically read on the label region of the optical disc.

2. The method of claim 1, wherein optically reading the marking on the label region comprises optically reading a marking on the label region representing an encryption key for the information stored on the data region of the optical disc.

3. The method of claim 1, wherein optically reading the marking on the label region comprises optically reading a marking on the label region representing a length of time the information stored on the data region of the optical disc is accessible.

4. The method of claim 1, wherein optically reading the marking on the label region comprises optically reading a marking on the label region representing an expiration date after which the information stored on the data region of the optical disc is inaccessible.

5. The method of claim 1, wherein optically reading the marking on the label region comprises optically reading a marking on the label region representing a number of times the information stored on the data region of the optical disc is accessible.

6. The method of claim 5, further comprising optically modifying the marking on the label region to reducing the number of times the information stored on the data region of the optical disc is accessible by one time.

7. The method of claim 1, wherein optically reading the marking on the label region comprises optically reading a marking on the label region indicating which parts of the information stored on the data region of the optical disc that are accessible.

8. The method of claim 7, further comprising optically modifying the marking on the label region of the optical disc to change the parts of the information stored on the data region of the optical disc that are accessible.

9. The method of claim 1, wherein optically reading the marking on the label region comprises determining whether the marking is present on the label region of the optical disc, such that access to the information stored on the data region of the optical disc is permitted when the marking is absent.

10. The method of claim 9, further comprising optically writing the marking on the label region of the optical disc to prevent further access to the information stored on the data region of the optical disc.

11. The method of claim 1, further comprising optically overwriting the marking on the label region of the optical disc to effectively erase the marking, to prevent further access to the information stored on the data region of the optical disc.

12. The method of claim 1, further comprising optically modifying the marking on the label region of the optical disc to modify access to the information stored on the data region of the optical disc.

13. The method of claim 12, where optically modifying the marking on the label region of the optical disc comprises optically overwriting the marking on the label region of the optical disc.

14. The method of claim 12, where optically modifying the marking on the label region of the optical disc comprises optically overwriting the marking on the label region of the optical disc to effectively erase the marking, and optically rewriting a modified version of the marking on the label region of the optical disc.

15. The method of claim 12, where optically modifying the marking on the label region of the optical disc comprises optically writing an additional part of the marking on the label region of the optical disc to result in a modified version of the marking on the label region of the optical disc.

16. The method of claim 1, further comprising optically modifying the marking on the label region of the optical disc to maintain access to the information stored on the data region of the optical disc.

17. An optical disc comprising:

a data region having information stored thereon; and

,

a label region having a marking optically written thereon to govern access to the information stored on the data region.

18. The optical disc of claim 17, wherein the data region is on a side of the optical disc and the label region is on an opposite side of the optical disc.

19. The optical disc of claim 17, wherein the data region and the label region are on a same side of the optical disc.

20. The optical disc of claim 17, wherein the label region further has an image within which the marking is interleaved to disguise the marking.

21. The optical disc of claim 17, wherein the marking optically written on the label region is a bar code.

22. The optical disc of claim 17, wherein the marking is a digital watermark.

23. The optical disc of claim 17, wherein the marking optically written on the label region is optically written on an inside diameter of the optical disc.

24. The optical disc of claim 17, wherein the marking optically written on the label region represents an encryption key for the information stored on the data region of the optical disc.

25. The optical disc of claim 17, wherein the marking optically written on the label region represents a number of times the information stored on the data region of the optical disc is accessible.

26. The optical disc of claim 17, wherein the marking optically written on the label region indicates which parts of the information stored on the data region of the optical disc that are accessible.

27. The optical disc of claim 17, wherein the marking optically written on the label region indicates an expiration date after which the information stored on the data region of the optical disc is inaccessible.

28. The optical disc of claim 17, wherein the marking optically written on the label region indicates a time period during which the information stored on the data region is accessible.

29. An optical disc comprising:

an optically writable label region; and

,

means on the optically writable label region for governing access to information.

30. The optical disc of claim 29, further comprising a data region having the information stored thereon.

31. The optical disc of claim 29, wherein the optically writable label region is an optically writable side of the optical disc.

32. The optical disc of claim 29, wherein the means comprises an optically readable marking.

33. The optical disc of claim 29, wherein the means comprises an optically readable bar code.

34. The optical disc of claim 29, wherein the means comprises an image within which an optically readable marking is interleaved to disguise the marking.

35. A method comprising:

storing information on a data region of an optical disc;

conveying the optical disc to a user; and

,

optically writing a marking on a label region of the optical disc that governs access to the information by the user.

36. The method of claim 35, further comprising providing the user access to the marking so that the marking is able to be optically written on the label region of the optical disc.

37. The method of claim 36, wherein providing the user access to the marking comprises enabling the user to download the marking over a communications network.
