Abstract

Improved hard disk drives of the invention comprise: a housing comprising an exterior surface; disk drive components enclosed within the housing for facilitating reading and recording of data at a desired location on at least one disk contained within the housing; and at least one continuous polymeric coating encapsulating the exterior surface of the housing. Methods of forming improved hard disk drives comprising a step of encapsulating the exterior surface of the hard disk drive housing with at least one polymeric coating are also disclosed.

Claims

1. A hard disk drive comprising:

a housing comprising an exterior surface;

disk drive components enclosed within the housing for facilitating reading and recording of data at a desired location on at least one disk contained within the housing; and

at least one continuous polymeric coating encapsulating the exterior surface of the housing.

2. The hard disk drive of claim 1, wherein the polymeric coating comprises polyurethane.

3. The hard disk drive of claim 1, wherein the exterior surface of the housing comprises at least one metal coating.

4. The hard disk drive of claim 3, wherein the polymeric coating comprises a decorative label that also protects the underlying at least one metal coating.

5. The hard disk drive of claim 1, wherein the polymeric coating comprises at least one graphic.

6. The hard disk drive of claim 1, wherein a major portion of the hard disk drive housing comprises a material that is lighter in weight than metal.

7. The hard disk drive of claim 1, wherein the polymeric coating has a minimum thickness of at least about 10 microns.

8. A method of forming the hard disk drive of claim 1, the method comprising steps of:

providing a base component of the hard disk drive housing;

providing a cover component of the housing;

mating the base component and the cover component to enclose the disk drive components for facilitating reading and recording of data at a desired location on at least one disk contained within the housing, wherein the enclosed housing comprises the exterior surface; and

encapsulating the exterior surface of the housing with at least one polymeric coating to form the at least one continuous polymeric coating encapsulating the exterior surface of the housing.

9. The method of claim 8, wherein the step of encapsulating the exterior surface of the housing comprises dip coating the housing to form the at least one continuous polymeric coating encapsulating the exterior surface of the housing.

10. The method of claim 8, wherein the step of encapsulating the exterior surface of the housing comprises spray coating the housing to form the at least one continuous polymeric coating encapsulating the exterior surface of the housing.

11. The method of claim 8, wherein the step of encapsulating the exterior surface of the housing comprises label coating the housing to form the at least one continuous polymeric coating encapsulating the exterior surface of the housing.

12. The method of claim 8, further comprising a step of forming at least one metal coating over at least a portion of the exterior surface of the housing prior to encapsulating the exterior surface of the housing with the at least one polymeric coating.

13. The method of claim 8, wherein the polymeric coating comprises polyurethane.

14. The method of claim 8, wherein the base component of the housing comprises plastic.

15. The method of claim 14, wherein the exterior surface of the housing comprises at least one metal coating.

16. The method of claim 8, wherein the cover component of the housing comprises plastic.

17. The method of claim 16, wherein the exterior surface of the housing comprises at least one metal coating.

18. The method of claim 8, wherein the polymeric coating comprises at least one graphic.

20. The method of claim 8, wherein a major portion of the hard disk drive housing comprises a material that is lighter in weight than metal.
