Media drive having a head positioning assembly utilizing a rotatable and slidable nut engaging a threaded screw

1. A media drive comprising:

a deck having a first threaded hole; and

a head positioning assembly including:

a baseplate disposed adjacent to the deck and having a mounting bracket that includes a first aperture;

a nut moveably disposed in the first aperture and having a second threaded hole; and

an adjustment screw that extends through the second threaded hole and includes first and second threaded portions;

wherein the nut rotates about an axis of rotation and slides within the first aperture to align the first and second threaded portions with the first and second threaded holes, respectively, to inhibit cross-threading when the adjustment screw is turned.

2. The media drive of claim 1 wherein the first aperture is defined by first and second generally planar surfaces disposed opposite each other and first and second curved surfaces extending from opposite ends of the first and second generally planar surfaces.

3. The media drive of claim 1 wherein the adjustment screw further comprises a tool engagement feature disposed at an end of the adjustment screw disposed opposite the first threaded portion.

4. The media drive of claim 1 wherein the adjustment screw further comprises an intermediate portion disposed between the first and second threaded portions, the intermediate portion having a smaller diameter than the second threaded hole.

5. The media drive of claim 1 wherein the adjustment screw further comprises an intermediate portion disposed between the first and second threaded portions, the intermediate portion having a smaller diameter than the first and second threaded portions.

6. The media drive of claim 1 wherein the nut has a generally cylindrical outer surface that permits the nut to rotate and slide within the first aperture.

7. The media drive of claim 1 wherein the mounting bracket further comprises first and second apertures that cooperate to receive the nut, the first and second apertures being coaxially arranged, spaced apart from each other, and disposed generally perpendicular to the deck.

8. The media drive of claim 1 wherein the nut further comprises a flange that limits movement of the nut along the axis when the flange contacts the mounting bracket.

9. The media drive of claim 1 further comprising a read/write head disposed adjacent to the baseplate.

10. The media drive of claim 1 wherein the second threaded hole is disposed generally perpendicular to the axis of rotation.

11. A media drive comprising:

a deck having a first threaded hole;

a head positioning assembly including:

a baseplate disposed adjacent to the deck and having a mounting bracket that includes a first aperture having first and second generally planar surfaces disposed opposite each other;

a nut moveably disposed in the first aperture and having a second threaded hole; and

an adjustment screw that extends through the second threaded hole and includes first and second threaded portions; and

a read/write head disposed adjacent to the head positioning assembly;

wherein the nut is rotatable about an axis of rotation and moveable along at least one of the first and second generally planar surfaces to align the first and second threaded portions with the first and second threaded holes, respectively, to inhibit cross-threading when the adjustment screw is rotated to position the read/write head.

12. The media drive of claim 11 wherein the adjustment screw further comprises an intermediate portion disposed between the first and second threaded portions, the intermediate portion having a smaller diameter than the first and second threaded portions.

13. The media drive of claim 12 wherein the intermediate portion has a smooth outer surface and a smaller diameter than the second threaded hole.

14. The media drive of claim 11 wherein the first threaded portion and the first threaded hole have a different thread pitch than the second threaded portion and the second threaded hole to improve adjustment resolution when positioning the read/write head.

15. The media drive of claim 11 wherein the nut further comprises first and second flat surfaces disposed adjacent to first and second ends of the second threaded hole, respectively.

16. The media drive of claim 11 wherein the nut further comprises a flange for limiting movement of the nut along the axis of rotation.

17. A media drive comprising:

a deck having a first threaded hole;

a read/write head; and

a head positioning assembly including:

a baseplate that receives the read/write head and is disposed adjacent to the deck, the baseplate having a mounting bracket that includes a first aperture;

a nut disposed along a first axis and extending through the first aperture, the nut having a second threaded hole disposed along a second axis; and

an adjustment screw that extends through the second threaded hole along the second axis;

wherein the read/write head is positioned by rotating the adjustment screw and the adjustment screw is positioned in a first direction by rotating the nut about the first axis, positioned in a second direction by sliding the nut within the first aperture, and positioned in a third direction by rotating the adjustment screw about the second axis.

18. The media drive of claim 17 wherein the adjustment screw further comprises a first threaded portion, a second threaded portion, and an intermediate portion disposed adjacent to the first and second threaded portions, wherein the intermediate portion is disposed within the second threaded hole when the first threaded portion engages the first threaded hole.

19. The media drive of claim 17 wherein the adjustment screw further comprises first and second threaded portions, wherein the first threaded portion is threaded into the first threaded hole before the second threaded portion is threaded into the second threaded hole.

20. The media drive of claim 19 wherein the baseplate is positioned in a non-parallel relationship with the deck when the first threaded portion is threaded into the first threaded hole.
