Claims
- 1. A shroud for blocking wind to an arm that positions a slider adjacent a recording surface of a disc that rotates in a predetermined direction in a disc drive housing to generate wind that aerodynamically supports the slider, the shroud comprising:
a mount for mounting to the housing; and a shield attached to the mount, the shield including
a first wall having a windward surface facing into the direction of rotation of the disc adjacent a windward side of the arm to shield the arm assembly from the wind when the arm positions the slider adjacent the disc.
- 2. The shroud of claim 1, wherein the shield further includes
a second wall perpendicular to the first wall and extending downwind of the windward surface between the arm and the first disc, the first and second walls together forming a low-wind region, and an opening into the region at a leeward side, the arm being receivable within the low-wind region to position the first slider adjacent the first disc.
- 3. The shroud of claim 2, further including:
a third wall perpendicular to the first wall and parallel to the second wall to define a slot for receiving the arm.
- 4. The shroud of claim 3, wherein the disc drive includes a second disc that rotates in the predetermined direction in the disc drive and the arm is positioned between the first-named and second discs to position the first slider adjacent the recording surface of the first-named disc and the second slider adjacent a recording surface of the second disc, the third wall extending downwind of the windward surface between the arm and the second disc.
- 5. The shroud of claim 4, wherein the disc drive housing further includes a second arm that positions a third slider adjacent a second recording surface of the first-named disc, the shroud further including:
a fourth wall having a windward surface facing into the direction of rotation of the first-named disc, a fifth wall perpendicular to the fourth wall and extending downwind of the windward surface between the second arm and the first-named disc, the fourth and fifth walls together forming a second low-wind region, and a second opening into the second region at a leeward side, the second arm being received within the second low-wind region to position the third slider adjacent the first-named disc.
- 6. The shroud of claim 2, wherein the arm is rotatable about an axis, and the opening includes
an arcuate edge having a radius from the axis of rotation of the arm, so that the first slider is positioned adjacent the first disc at the leeward side of the shroud at rotational positions of the arm.
- 7. The shroud of claim 2, wherein the windward surface is curved.
- 8. A disc drive comprising:
a housing; a first rotatable disc supported within the housing for rotation in a predetermined direction, the first disc having a first recording surface; an arm supported within the housing for rotation about an axis; a first slider supported by the arm and arranged to be positioned adjacent the first recording surface of the first disc; and a shroud including:
a first wall having a windward surface facing into the direction of rotation of the first disc, a second wall perpendicular to the first wall and extending downwind of the windward surface between the arm and the first disc, the first and second walls together forming a low-wind region, an opening into the region at a leeward side, the arm being receivable within the low-wind region to position the first slider adjacent the first disc, and a mount mounting the shroud to the housing.
- 9. The disc drive of claim 8, further including:
a second rotatable disc supported within the housing for rotation in the predetermined direction, the second disc having a first recording surface, a second slider supported by the arm and arranged to be positioned adjacent the first recording surface of the second disc, the shroud further including:
a third wall perpendicular to the first wall and parallel to the second wall to define a slot for receiving the arm, the third wall extending downwind of the windward surface between the arm and the second disc.
- 10. The disc drive of claim 9, further including:
a second arm supported within the housing for rotation about the axis, a third slider supported by the second arm and arranged to be positioned adjacent a second recording surface of the first disc, the shroud further including:
a fourth wall having a windward surface facing into the direction of rotation of the first disc, a fifth wall perpendicular to the fourth wall and extending downwind of the windward surface between the second arm and the first disc, the first and second walls together forming a second low-wind region, and a second opening into the second region at a leeward side, the second arm being received within the second low-wind region to position the third slider adjacent the first disc.
- 11. The shroud of claim 8, wherein the opening includes
an arcuate edge having a radius from the axis of rotation of the arm, so that the first slider is positioned adjacent the first disc at the leeward side of the shroud at rotational positions of the arm.
- 12. The shroud of claim 8, wherein the windward surface is curved.
- 13. A shroud for use with an arm that positions a device in a windy environment, the shroud comprising:
a mount for mounting the shroud to a housing; and means for shielding the arm from wind while the arm positions the device in the windy environment.
- 14. The shroud of claim 13, wherein the means for shielding includes:
a first wall defining a windward surface, a second wall perpendicular to the first wall, the first and second walls together forming a low-wind region, and a first opening to the region at a leeward side, the arm being receivable within the low-wind region to position the device within the windy environment.
- 15. The shroud of claim 14, further including:
a third wall perpendicular to the first wall and parallel to the second wall to define a low-wind slot for receiving the arm.
- 16. The shroud of claim 15, wherein the arm is rotatable about an axis, and the opening includes:
an edge having a radius from the axis of rotation of the arm, so that the device is positioned in the windy environment at the leeward side of the shroud at rotational positions of the arm.
- 17. The shroud of claim 16, further including:
a second opening to the region at a side opposite the windward side to permit rotation of the arm outside the region.
- 18. The shroud of claim 14, wherein the arm is rotatable about an axis, and the opening includes:
an edge having a radius from the axis of rotation of the arm, so that the device is positioned in the windy environment at the leeward side of the shroud at rotational positions of the arm.
- 19. The shroud of claim 18, further including:
a second opening to the region at a side opposite the windward side to permit rotation of the arm outside the region.
