Abstract

Claims (27)

1. A disk drive enclosure comprising

an enclosure main body forming an interior region, the interior region having a Voice Coil Motor (VCM) assembly receiving portion configured to hold a VCM assembly;

at least one cover member configured to engage the enclosure main body and cover the interior region of the enclosure main body, and expose at least a portion of the VCM assembly receiving portion;

wherein the cover member is configured to engage and be supported by an upper yoke of the VCM assembly disposed in the VCM assembly receiving portion of the enclosure main body; and

a conformal sealing member configured to cover substantially all of: the VCM assembly, including the upper yoke, the cover member and the enclosure main body to substantially seal the disk drive enclosure,

wherein the VCM assembly receiving portion of the enclosure main body comprises a side wall configured to extend upward to have a height substantially equal to the height of the VCM assembly on at least one side of the VCM assembly.

2. The drive enclosure of claim 1 , wherein the cover member is configured to be supported by the VCM assembly at a location nearest a pivot point of an actuator arm disposed within the interior region of the disk drive enclosure.

3. The drive enclosure of claim 1 , wherein the cover member is configured to be supported by a tab extending from a top plate of the VCM assembly, the tab at least partially covering a portion of a head stack assembly disposed adjacent to the VCM assembly.

4. The drive enclosure of claim 3 , wherein the cover member comprises a tab extending toward the VCM assembly configured to engage the tab extending from the VCM assembly.

5. The drive enclosure of claim 4 , wherein the cover member is configured to be received in a recess formed in the tab extending from the top plate of the VCM assembly.

6. The drive enclosure of claim 1 , wherein the side wall of the VCM assembly receiving portion is configured to extend upward to have a height substantially equal to the height of the VCM assembly on at least two sides of the VCM assembly.

7. The drive enclosure of claim 1 , wherein the sealing member is a thin-film member and is adhesively attached to the drive enclosure.

8. The drive enclosure of claim 1 , wherein the VCM assembly comprises a top plate having a tab that extends from the VCM assembly to at least partially cover a latch mechanism for an actuator arm disposed within the interior region of the disk drive enclosure.

9. A disk drive assembly comprising:

a disk drive enclosure comprising

an enclosure main body forming an interior region, the interior region having a Voice Coil Motor (VCM) assembly receiving portion configured to hold a VCM assembly; and

a cover member configured to engage the enclosure main body and cover the interior region of the enclosure main body, and expose at least a portion of the VCM Assembly receiving portion;

a VCM assembly disposed within the VCM assembly receiving portion of the enclosure main body, the VCM assembly comprising an upper yoke formed by an upper plate, the upper yoke forming at least one cover supporting member configured to engage and support the cover member; and

a conformal sealing member configured to cover substantially all of: the VCM assembly, including the upper yoke, the cover member and the enclose enclosure main body to substantially seal the disk drive assembly,

wherein the VCM assembly receiving portion of the enclosure main body comprises a side wall configured to extend upward to have a height substantially equal to the height of the VCM assembly on at least one side of the VCM assembly.

10. The drive assembly of claim 9 , wherein the cover supporting member is disposed on a side of the VCM assembly nearest a pivot point of an actuator arm disposed within the interior region of the disk drive enclosure.

11. The drive assembly of claim 9 , wherein the cover supporting member of the VCM assembly comprises a tab extending from a top plate of the VCM assembly to at least partially cover a portion of a head stack assembly disposed adjacent the VCM assembly.

12. The drive assembly of claim 11 , wherein the cover member comprises a tab extending toward the VCM assembly configured to engage the tab of the cover supporting member of the VCM assembly.

13. The drive assembly of claim 12 , wherein the cover supporting member comprises a recess formed in the tab extending from the top plate of the VCM assembly, the recess configured to receive the tab of the cover member.

14. The drive assembly of claim 9 , wherein the side wall of the VCM assembly receiving portion is configured to extend upward to have a height substantially equal to the height of the VCM assembly on at least two sides of the VCM assembly.

15. The drive assembly of claim 9 , wherein the sealing member is a thin-film member and is adhesively attached to the drive assembly.

16. The drive assembly of claim 9 , wherein the VCM assembly comprises a top plate having a tab that extends from the VCM assembly to at least partially cover a latch mechanism for an actuator arm disposed within the interior region of the disk drive enclosure.
