Abstract

A data recording element includes a data recording medium and a recording medium support; data recorded on the data recording medium; and c) a unique ID corresponding to the data on the recording medium, recorded on the recording medium support.

Claims

1. A data recording element, comprising:

a) a data recording medium and a recording medium support;

b) data recorded on the data recording medium; and

c) a unique ID corresponding to the data on the recording medium, recorded on the recording medium support.

2. The data recording element claimed in claim 1, wherein the data recorded on the data recording medium includes the unique ID.

3. The data recording element claimed in claim 1, wherein the unique ID is derived from data recorded on the data recording medium.

4. The data recording element claimed in claim 3, wherein the unique ID is a checksum of the data recorded on the data recording medium.

5. The data recording element claimed in claim 1, wherein the unique ID is recorded in invisible ink.

6. The data recording element claimed in claim 5, wherein the data recording element is an optical disc having a data side and a label side and the unique ID is recorded on the label side of the disc.

7. The data recording element claimed in claim 5, wherein the data recording element is a magnetic tape cassette, the data storage medium is magnetic tape, the recording medium support is a plastic case, and the unique ID is recorded on the plastic case.

8. The data recording element claimed in claim 5, wherein the data recording element is a magnetic disc cassette, the data storage medium is a magnetic disc, the recording medium support is a sleeve, and the unique ID is recorded on the sleeve.

9. The data recording element claimed in claim 5, wherein the data recording element is a solid state memory cartridge, the data storage medium is a solid state memory, the recording medium support is a plastic case surrounding an integrated circuit package, and the unique ID is recorded on the plastic case.

10. The data recording element claimed in claim 1, wherein the unique ID is recorded steganographically in an image on the recording medium support.

11. A system for preventing the reading of data from a counterfeit recording, comprising:

a) a data recording element, including;

i) a data recording medium and a recording medium support;

ii) data recorded on the data recording medium; and

iii) a unique ID corresponding to the data on the recording medium, recorded on the recording medium support; and

b) a data reader for reading data from the data recording element, the data reader including;

i) a first reading device for reading the data on the recording medium;

ii) a second reading device for reading the unique ID recorded on the recording medium support; and

iii) logic and control means for comparing the data read from the data recording medium and the unique ID and allowing output of the data only if the unique ID corresponds to the data read from the data recording medium.

12. The system claimed in claim 11, wherein the data recorded on the data recording medium includes the unique ID.

13. The system claimed in claim 11, wherein the unique ID is derived from data recorded on the data recording medium.

14. The system claimed in claim 13, wherein the unique ID is a checksum of the data recorded on the data recording medium.

15. The system claimed in claim 11, wherein the unique ID is recorded in invisible ink.

16. The system claimed in claim 15, wherein the data recording element is an optical disc having a data side and a label side and the unique ID is recorded on the label side of the disc.

17. The system claimed in claim 15, wherein the data recording element is a magnetic tape cassette, the data storage medium is magnetic tape, the recording medium support is a plastic case, and the unique ID is recorded on the plastic case.

18. The system claimed in claim 15, wherein the data recording element is a magnetic disc cassette, the data storage medium is a magnetic disc, the recording medium support is a sleeve, and the unique ID is recorded on the sleeve.

19. The system claimed in claim 15, wherein the data recording element is a solid state memory cartridge, the data storage medium is a solid state memory, the recording medium support is an integrated circuit package, and the unique ID is recorded on the integrated circuit package.

20. The system claimed in claim 11, wherein the unique ID is recorded steganographically in an image on the recording medium support.
