Abstract

Embodiments described herein relate to a disk drive coupler for reducing particulates in a disk drive. In some embodiments, the disk drive includes a first component having a top surface and a bottom surface, the first component defining an aperture with an interior surface between the top surface and the bottom surface, and a channel on at least one of the top surface, the bottom surface, and the interior surface. In some embodiments, the disk drive coupler includes a fastener configured to be received within the aperture and is configured to secure the first component to a second component. The channel is configured to permit the drawing of air from at least one of the aperture, the top surface, and the bottom surface of the first component before and after the fastener secures the first component to the second component.

Claims (21)

1. A disk drive comprising:

a disk drive base having a coupling portion defining a bore; and

a VCM plate comprising a top surface and_configured to be coupled to the disk drive base, the VCM plate forming an aperture configured to receive a fastener to couple the VCM plate to the disk drive base via the coupling portion, the VCM plate having a channel formed along the aperture, the channel having a cross-sectional dimension greater than that of a head of the fastener such that air can be drawn from the top surface immediately adjacent the fastener and through the channel when the fastener is received through the aperture and couples the VCM plate to the disk drive base.

2. The disk drive of claim 1 , wherein the channel comprises at east one slot extending along an inner surface of the aperture.

3. The disk drive of claim 2 , wherein the channel a plurality of slots.

4. The disk drive of claim 3 , wherein the channel comprises 3 slots.

5. The disk drive of claim 2 , wherein the channel comprises 4 slots.

6. The disk drive of claim 1 , wherein the channel comprises at least one slot extending along the aperture in a direction that is substantially parallel with a central axis of the aperture.

7. The disk drive of claim 1 , wherein the channel provides a pathway from the top surface of the plate to a bottom surface of the plate unobstructed by the fastener head when the fastener couples the plate to the disk drive base.

8. The disk drive of claim 7 , wherein the channel extends along the top surface, opposite the disk drive base, of the plate.

9. The disk drive of claim 7 , wherein the channel extends along a bottom surface of the plate adjacent to the coupling portion of the disk drive base.

10. The disk drive of claim 1 , wherein the channel extends in a direction along the plate that is substantially transverse to a central as of the aperture.

11. A disk drive coupler for reducing particulates in a disk drive, the coupler comprising:

a plate having a top surface and a bottom surface, the plate defining an aperture with an interior surface between the top surface and the bottom surface, the plate having a channel along at least the top surface, and the interior surface; and

a fastener configured to be received within the aperture and configured to secure the plate to a portion of a disk drive;

wherein the channel is configured to run from the aperture and to radially extend, within the top surface, beyond an outermost cross-sectional measurement of the fastener so as to permit the drawing of air to the top surface of the plate from at least the aperture when the fastener secures the plate to the portion of the disk drive.

12. The disk drive coupler of claim 11 , wherein the channel comprises at least one slot extending along an inner surface of the aperture.

13. The disk drive coupler of claim 12 , wherein the channel comprises a plurality of slots.

14. The disk drive coupler of claim 11 , wherein the channel comprises at least one slot extending along the aperture in a direction that is substantially parallel with a central axis of the aperture.

15. The disk drive coupler of claim 11 , wherein the channel extends in a direction along the plate that is substantially transverse to a central axis of the aperture.

16. The disk drive coupler of claim 11 , wherein the channel is configured to permit the drawing of air to the top surface both during and after the fastener secures the plate to the portion of the disk drive.
