Abstract

According to one embodiment of the invention, a system for source tagging an optical storage device includes the optical storage device having a first portion adapted to store information and a second portion adjacent the first portion, and an electronic article surveillance tag associated with the second portion.

Claims

1. A system for source tagging an optical storage device, comprising:

an optical storage device having a first portion adapted to store information and a second, non-information storage portion adjacent and laterally inward of the first portion; and

an electronic article surveillance tag and an associated antenna embedded within a layer of the second portion;

wherein the electronic article surveillance tag and antenna are embedded within and surrounded by the layer of the second portion during an injection molding process.

2. The system of claim 1, wherein the optical storage device is a CD.

3. The system of claim 1, wherein the optical storage device is a DVD.

4. The system of claim 1, wherein the second portion is annular and is surrounded by the first portion.

5. The system of claim 4, further comprising an aperture formed in the optical storage device and surrounded by the second portion.

6. The system of claim 4, wherein the electronic article surveillance tag includes an antenna extending around a circumferential length of the second portion.

7. The system of claim 1, wherein the electronic article surveillance tag and antenna are embedded within and surrounded by the layer that is part of a substrate of the second portion.

8. The system of claim 1, wherein the electronic article surveillance tag is selected from the group consisting of an RF tag, an RFID tag, an EM tag, and an AM tag.

9. The system of claim 1, wherein the layer is a non-laminated layer.

10. The system of claim 1, wherein the layer is a homogeneous layer.

11. The system of claim 1, wherein the electronic article surveillance tag is at least partially embedded within the layer.

12. The system of claim 1, wherein the electronic article surveillance tag is completely embedded within the layer.

13. The system of claim 1, wherein the layer is a substrate.

14. The system of claim 1, wherein the layer is a single layer.

15. The system of claim 1, wherein the layer is one of a plurality of layers.

16. A method for source tagging an optical storage device, comprising:

providing an optical storage device with a first portion adapted to store information and an annular second, non-information storage portion disposed within the first portion; and

embedding an electronic article surveillance tag and an associated antenna so that they are surrounded by a layer of within the second portion during an injection molding process.

17. The method of claim 16, further comprising providing an aperture with the optical storage device, the aperture surrounded by the second portion.

18. The method of claim 16, wherein embedding the electronic article surveillance tag and associated antenna in the second portion comprises embedding the electronic article surveillance tag and associated antenna so that they are surrounded by the layer that is part of a substrate of the second portion.

19. The method of claim 16, wherein the antenna of the electronic article surveillance tag extends around a circumferential length of the second portion.

20. The method of claim 16, wherein the electronic article surveillance tag is selected from the group consisting of an RF tag, an RFID tag, an EM tag, and an AM tag.

21. The method of claim 16, wherein the optical storage device is a CD.

22. The method of claim 16, wherein the optical storage device is a DVD.

23. An optical storage disc, comprising:

an outer annular portion adapted to store information;

an inner annular, non-information storage portion adjacent and laterally inward of the outer annular portion; and

an electronic article surveillance tag embedded within a layer of the inner annular portion;

an antenna associated with the electronic article surveillance tag and embedded within the layer of the inner annular portion;

wherein the electronic article surveillance tag is selected from the group consisting of an RF tag, an RFID tag, an EM tag, and an AM tag; and

wherein the electronic article surveillance tag and associated antenna are embedded within the layer of the inner annular portion during an injection molding process.

24. The optical storage disc of claim 23, wherein the optical storage disc is a CD.

25. The optical storage disc of claim 23, wherein the optical storage disc is a DVD.

26. The optical storage disc of claim 23, wherein the antenna extends around a circumferential length of the inner annular portion.

27. The optical storage disc of claim 23, wherein the layer of the inner annular portion is formed from a polymer.
