Abstract

According to one embodiment, a calibration assembly includes an outer layer having at least one calibration trench extending along a y-axis, and an encapsulation layer within the calibration trench. The encapsulation layer has a plurality of nanoparticles spaced apart along said y-axis of said at least one calibration trench. Each of said plurality of nanoparticles are provided at known y-axis locations in said calibration trench, and each of the plurality of nanoparticles have a known magnetic property.

First claim

What is claimed is:

1. A calibration assembly comprising:
an outer layer having at least one calibration trench extending along a y-axis; and
an encapsulation layer within said calibration trench, said encapsulation layer having a plurality of nanoparticles spaced apart along said y-axis of said at least one calibration trench,
wherein each of said plurality of nanoparticles are provided at known y-axis locations within said calibration trench, and
wherein each of said plurality of nanoparticles have a known magnetic property.

2. The calibration assembly of claim 1 , further comprising magnetic servo alignment marks.

3. The calibration assembly of claim 2 , wherein said calibration assembly further comprises a servo alignment trench in said outer layer, said servo alignment trench parallel with said calibration trench.

4. The calibration assembly of claim 1 , wherein said outer layer is selected from the group consisting of diamond-like-carbon, polytetrafluoroethylene aluminum oxide, and polyamides.

5. The calibration assembly of claim 1 , wherein said calibration assembly further comprises a base layer and wherein said base layer is selected from the group consisting of gold, silicon, and silicon oxide.

6. A calibration assembly comprising:
an outer layer having at least one calibration trench extending along a y-axis; and
an encapsulation layer within said calibration trench, said encapsulation layer having a plurality of nanoparticles spaced apart along said y-axis of said at least one calibration trench,
wherein each of said plurality of nanoparticles are encapsulated within said encapsulation layer,
wherein each of said plurality of nanoparticles are provided at known y-axis locations in said calibration trench, and
wherein each of said plurality of nanoparticles have a known magnetic property.

7. The calibration assembly of claim 6 , further comprising magnetic servo alignment marks.

8. The calibration assembly of claim 7 , wherein said calibration assembly further comprises a servo alignment trench in said outer layer, said servo alignment trench parallel with said calibration trench.

9. The calibration assembly of claim 6 , wherein said outer layer is selected from the group consisting of diamond-like-carbon, polytetrafluoroethylene aluminum oxide, and polyamides.

10. The calibration assembly of claim 6 , wherein said calibration assembly further comprises a base layer and wherein said base layer is selected from the group consisting of gold, silicon, and silicon oxide.

11. A calibration assembly comprising:
an outer layer having at least one calibration trench extending along a y-axis; and
an encapsulation layer within said calibration trench, said encapsulation layer having a plurality of nanoparticles spaced apart along said y-axis of said at least one calibration trench,
wherein said encapsulation layer comprising a cured polymer resin and each of said plurality of nanoparticles being encapsulated within said cured polymer resin,
wherein each of said plurality of nanoparticles are provided at known y-axis locations in said calibration trench, and
wherein each of said plurality of nanoparticles have a known magnetic property.

12. The calibration assembly of claim 11 , further comprising magnetic servo alignment marks.

13. The calibration assembly of claim 12 , wherein said calibration assembly further comprises a servo alignment trench in said outer layer, said servo alignment trench parallel with said calibration trench.

14. The calibration assembly of claim 11 , wherein said outer layer is selected from the group consisting of diamond-like-carbon, polytetrafluoroethylene aluminum oxide, and polyamides.

15. The calibration assembly of claim 11 , wherein said calibration assembly further comprises a base layer and wherein said base layer is selected from the group consisting of gold, silicon, and silicon oxide.
