A magnetic disk conditioner is provided. The disk conditioner comprises a tunnel having a top inside surface and a bottom inside surface. A first array of magnets of alternating polarity is coupled to the top inside surface, the first array of magnets comprising a first portion of reduced field strength. The tunnel further comprises a second array of magnets of alternating polarity coupled to the bottom inside surface, the second array of magnets comprising a second portion of reduced field strength and separated from the first array of magnets by a distance that allows a plurality of disks to simultaneously pass through the tunnel for conditioning. |

| Claim: |
1. A magnetic disk conditioner comprising: a tunnel comprising a top inside surface and a bottom inside surface; a first array of magnets of alternating polarity coupled to said top inside surface, said first array of magnets comprising a first portion of reduced field strength; and a second array of magnets of alternating polarity coupled to said bottom inside surface, said second array of magnets comprising a second portion of reduced field strength and separated from said first array of magnets by a distance that allows a plurality of disks to simultaneously pass through said tunnel for conditioning. |
| Claim: |
2. The magnetic disk conditioner as described in claim 1 wherein said first array of magnets comprises larger magnets at a first end and smaller magnets at a second end, said second end comprising said first portion of reduced field strength. |
| Claim: |
3. The magnetic disk conditioner as described in claim 1 wherein said second array of magnets comprises larger magnets at a first end and smaller magnets at a second end, said second end comprising said second portion of reduced field strength. |
| Claim: |
4. The magnetic disk conditioner as described in claim 1 wherein at least one of said magnets is an electromagnet. |
| Claim: |
5. The magnetic disk conditioner as described in claim 1 wherein one magnet of said first array of magnets is a first polarity type and is coincident with one magnet of said first polarity type of said second array of magnets. |
| Claim: |
6. The magnetic disk conditioner as described in claim 1 wherein one magnet of said first array of magnets is a first polarity type and is offset from one magnet of said first polarity type of said second array of magnets. |
| Claim: |
7. The magnetic disk conditioner as described in claim 1 wherein said first array of magnets comprises similar magnetic characteristics of said second array of magnets. |
| Claim: |
8. A method for magnetically conditioning a plurality of disks comprising: accessing a magnetic disk conditioner comprising: a tunnel comprising a top inside surface, a bottom inside surface, a first end and a second end; a first array of magnets of alternating polarity coupled to said top inside surface, said first array of magnets comprising a first portion of reduced field strength at said second end of said tunnel; and a second array of magnets of alternating polarity coupled to said bottom inside surface, said second array of magnets comprising a second portion of reduced field strength at said second end of said tunnel; and passing simultaneously a plurality of disk drive disks through said tunnel from said first end of said tunnel to said second end of said tunnel. |
| Claim: |
9. The method as described in claim 8 wherein said first array of magnets comprises larger magnets at said first end of said tunnel and smaller magnets at said second end of said tunnel. |
| Claim: |
10. The method as described in claim 8 wherein said second array of magnets comprises larger magnets at said first end of said tunnel and smaller magnets at a second end of said tunnel. |
| Claim: |
11. The method as described in claim 8 wherein at least one of said magnets is an electromagnet. |
| Claim: |
12. The method as described in claim 8 wherein one magnet of said first array of magnets is a first polarity type and is coincident with one magnet of said first polarity type of said second array of magnets. |
| Claim: |
13. The method as described in claim 8 wherein one magnet of said first array of magnets is a first polarity type and is offset from one magnet of said first polarity type of said second array of magnets. |
| Claim: |
14. The method as described in claim 8 wherein said first array of magnets comprises similar magnetic characteristics of said second array of magnets. |
| Claim: |
15. A method for magnetically conditioning a cartridge comprising a plurality of disks comprising: accessing a plurality of disks; moving said plurality of disks through a vessel, said vessel comprising a first array of magnets coupled to a first inside surface of said vessel and a second array of magnets coupled to a second inside surface of said vessel opposite said first inside surface of said vessel; applying a magnetic force comprising alternating polarities to said plurality of disks wherein as said plurality of disks move from a first end of said vessel to a second end of said vessel, said magnetic force is reduced. |
| Claim: |
16. The method as described in claim 15 wherein said first array of magnets comprises larger magnets at said first end of said vessel and smaller magnets at said second end of said vessel. |
| Claim: |
17. The method as described in claim 15 wherein said second array of magnets comprises larger magnets at said first end of said vessel and smaller magnets at said second end of said vessel. |
| Claim: |
18. The method as described in claim 15 wherein at least one of said magnets is an electromagnet. |
| Claim: |
19. The method as described in claim 15 wherein one magnet of said first array of magnets is a first polarity type and is coincident with one magnet of said first polarity type of said second array of magnets. |
| Claim: |
20. The method as described in claim 15 wherein one magnet of said first array of magnets is a first polarity type and is offset from one magnet of said first polarity type of said second array of magnets. |
| Claim: |
21. The method as described in claim 15 wherein said first array of magnets comprises similar magnetic characteristics of said second array of magnets. |
