Abstract

A method of assembling a hard disk drive comprises steps of: sealing an interface of the base and the cover of an enclosed housing with an infrared-transmissive tape; filling the enclosed housing with a desired gaseous medium; optionally, testing the hard disk drive; and, optionally; re-working the hard disk drive. Preferably, the enclosed housing is free of rubber gasket materials between the base and the cover. A hermetically sealed hard disk drive of the invention comprises: a housing comprising a base and a cover; and disk drive components enclosed within the housing for facilitating reading and recording of data at any desired location on at least one disk contained within the housing, wherein the hard disk drive is free of rubber gasket materials between the base and the cover.

Claims

1. A method of assembling a hard disk drive, the method comprising steps of:

providing a base component of a housing of the hard disk drive;

providing a cover component of the housing;

mating the base component and the cover component to form an enclosed housing that encloses disk drive components for facilitating reading and recording of data at any desired location on at least one disk contained within the enclosed housing;

sealing an interface of the base component and the cover component of the enclosed housing with an infrared-transmissive adhesive tape;

filling the enclosed housing with a desired gaseous medium;

optionally, testing the hard disk drive; and

optionally, re-working the hard disk drive.

2. The method of claim 1, further comprising a step of irreversibly hermetically sealing the hard disk drive.

3. The method of claim 2, wherein the step of irreversibly hermetically sealing the hard disk drive comprises using through transmission infrared bonding to mechanically couple the base component and the cover component.

4. The method of claim 1, wherein the infrared-transmissive adhesive tape remains on the hard disk drive during the step of irreversibly hermetically sealing the hard disk drive.

5. The method of claim 1, wherein at least one of the base component and the cover component comprises plastic.

6. The method of claim 5, wherein the plastic is polycarbonate or polybutylterepthalate.

7. The method of claim 1, wherein each of the base component and the cover component comprises plastic.

8. The method of claim 1, wherein the step of mating the base component and the cover component to enclose disk drive components results in a portion of the enclosed housing comprising an overlap of the base component and the cover component.

9. The method of claim 8, wherein an outer of the base component and the cover component in the overlap is infrared-transmissive.

10. The method of claim 9, further comprising a step of irreversibly hermetically sealing the hard disk drive, wherein the step of irreversibly hermetically sealing the hard disk drive comprises using through transmission infrared bonding to mechanically couple the base component and the cover component at the overlap.

11. The method of claim 1, wherein the enclosed housing is free of rubber gasket materials between the base component and the cover component.

12. The method of claim 1, wherein the infrared-transmissive adhesive tape is adhered to the enclosed housing so that the infrared-transmissive adhesive tape covers a seam formed by mating of the cover component and the base component.

13. The method of claim 1, wherein the infrared-transmissive adhesive tape is adhered to the enclosed housing in a single piece.

14. The method of claim 1, wherein the infrared-transmissive adhesive tape is adhered to the enclosed housing in multiple pieces.

15. The method of claim 1, wherein more than one infrared-transmissive adhesive tape is adhered to the enclosed housing.

16. The method of claim 1, wherein the infrared-transmissive adhesive tape remains on the hard disk drive during the optional step of re-working the hard disk drive.

17. The method of claim 1, further comprising the steps of:

after re-working the hard disk drive, reforming and resealing the enclosed housing with another infrared-transmissive adhesive tape; and

re-testing the hard disk drive after re-working the hard disk drive.

18. The method of claim 1, wherein the infrared-transmissive adhesive tape comprises a backing and an adhesive layer and wherein the adhesive layer in the infrared-transmissive adhesive tape is anchored to the backing in the infrared-transmissive adhesive tape at a greater strength than it is anchored to a surface on the hard disk drive on which the infrared-transmissive adhesive tape is used.

19. The method of claim 1, wherein the infrared-transmissive adhesive tape is free of metallic or other components that block transmission of infrared radiation.

20. A method of assembling a hard disk drive, the method comprising steps of:

providing a base component of a housing of the hard disk drive;

providing a cover component of the housing;

mating the base component and the cover component to form an enclosed housing that encloses disk drive components for facilitating reading and recording of data at any desired location on at least one disk contained within the enclosed housing;

sealing an interface of the base component and the cover component of the enclosed housing with an infrared-transmissive adhesive tape;

filling the enclosed housing with a desired gaseous medium;

testing the hard disk drive;

optionally, re-working the hard disk drive; and

irreversibly hermetically sealing the hard disk drive using through transmission infrared bonding to mechanically couple the base component and the cover component.
