Magnetizing inductor and a method for producing a magnetizing inductor
An improved print head for use by a magnetic printer consists of multiple flat metal layers that form a flat metal inductor coil about a hole having a first diameter on a first side of the print head and having a second diameter smaller than the first diameter on a second side of the print head.
1. A print head for magnetically printing a magnetic source into a magnetizable material comprising:
a first conductor layer on a first side of a print head; and
a second conductor layer on a second side of said print head that is opposite said first side, said first conductor layer and said second conductor layer forming a flat metal inductor coil about a hole, said hole having a first diameter on said first side of said print head and having a second diameter on said second side of said print head, said second diameter being smaller than said first diameter.
2. The print head of claim 1 , wherein the shape of the print head conforms to different shaped surfaces.
3. The print head of claim 1 , wherein said first conductor layer has a first thickness and said second conductor layer has a second thickness less than said first thickness.
4. The print head of claim 3 , wherein said first thickness and second thickness are proportional to said first diameter and said second diameter.
5. The print head of claim 1 , wherein said hole is a conically-shaped hole.
6. The print head of claim 1 , wherein said hole is a step-shaped hole.
7. The print head of claim 1 , further comprising:
at least one additional conductor layer between said first conductor layer and said second conductor layer.
8. The print head of claim 7 , wherein each conductor layer of said first conductor layer, said second conductor layer, and said at least one additional conductor layer has a funnel-like shape.
9. The print head of claim 7 , wherein said hole has a third diameter corresponding to said at least one additional conductor layer, said third diameter being smaller than said first diameter and larger than said second diameter.
10. The print head of claim 9 , wherein a thickness of each conductor layer of said first conductor layer, said second conductor layer, and said at least one additional conductor layer is proportional to the diameter of said hole corresponding to each conductor layer.
11. The print head of claim 7 , wherein each conductor layer of said first conductor layer, said second conductor layer, and said at least one additional conductor layer has a different thickness.
12. The print head of claim 1 , wherein said first conductor layer and said second conductor layer each comprise a metal.
13. The print head of claim 12 , wherein said metal comprises copper.
14. The print head of claim 1 , wherein said flat metal inductor coil has a concave shape.
15. The print head of claim 1 , wherein said flat metal inductor coil has a concave shape.
16. The print head of claim 1 , wherein said print head comprises four conductor layers.
17. The print head of claim 1 , wherein said print head comprises six conductor layers.
18. The print head of claim 1 , wherein said first conductor layer and said second conductor layer each have a funnel-like shape.
19. The print head of claim 1 , further comprising:
a first tab for connecting said first conductor layer to wiring of a magnetization subsystem.
20. The print head of claim 1 , further comprising:
a second tab for connecting said second conductor layer to wiring of a magnetization subsystem.
