Abstract

Examples of slide-in ramps for hard-disk drives are disclosed. In one example according to aspects of the present disclosure, a slide-in ramp includes: a ramp body, a head load/unload section connected to the ramp body, and a slot defined in the ramp body. The slot includes a first portion and a second portion. A first upper surface of the ramp body surrounds the first portion of the slot at a top side of the ramp body, and a second upper surface of the ramp body surrounds the second portion of the slot at the top side of the ramp body. The second upper surface is non-coplanar with the first upper surface according to various examples.

First claim

That which is claimed is:

1. A slide-in ramp comprising:
a ramp body;
a head load/unload section connected to the ramp body;
a slot defined in the ramp body, the slot including a first portion and a second portion, a first upper surface of the ramp body surrounding the first portion of the slot at a top side of the ramp body, and a second upper surface of the ramp body surrounding the second portion of the slot at the top side of the ramp body, the second upper surface being non-coplanar with the first upper surface; and
a lip defined by the ramp body between the first upper surface and the second upper surface, the lip having an arcuate shape configured to secure the slide-in ramp axially and rotationally by engaging a screw installed in the second portion of the slot, wherein the slot has a slot width and a slot length, wherein the slot length is greater than the slot width, and wherein the slot length extends in a direction substantially parallel to the head load/unload section.

2. The slide-in ramp of claim 1 , wherein the slide-in ramp is monolithically formed.

3. The slide-in ramp of claim 1 , wherein the lip extends from a side of the slot to an end of the ramp body.

4. The slide-in ramp of claim 1 , wherein the lip extends from a first side of the slot to a second side of the slot, and wherein the first upper surface surrounds the second upper surface.

5. The slide-in ramp of claim 1 , wherein the lip is a tapered surface extending between the first upper surface and the second upper surface.

6. The slide-in ramp of claim 1 , wherein the first upper surface extends from a first end of the ramp body to the lip between the first upper surface and the second upper surface and wherein the second upper surface extends from a second end of the ramp body to the lip.

7. The slide-in ramp of claim 1 , wherein the second upper surface is recessed into the ramp body relative to the first upper surface.

8. The slide-in ramp of claim 1 , wherein the lip is shaped complimentary to a radius of curvature of a screw head of the screw.

9. A method comprising:
positioning a slide-in ramp in a hard disk drive device, the slide-in ramp including
a ramp body,
a head load/unload section connected to the ramp body,
a slot defined in the ramp body, the slot including a first portion and a second portion, a first upper surface of the ramp body surrounding the first portion of the slot at a top side of the ramp body, a second upper surface of the ramp body surrounding the second portion of the slot at the top side of the ramp body, and
a lip defined between the first upper surface and the second upper surface;

inserting a screw in the first portion of the slot; and
sliding the slide-in ramp such that the screw is positioned in the second portion of the slot and engaged with the lip.

10. The method of claim 9 , wherein sliding the slide-in ramp includes contacting the ramp body with a datum plane of the hard disk drive device such that the lip and the datum plane hold the screw in place in the second portion of the slot.

11. The method of claim 9 , wherein tightening of the screw slides the slide-in ramp such that the screw is positioned in the second portion of the slot and engaged with the lip.

12. The method of claim 9 , wherein the lip is a tapered surface extending between the first upper surface and the second upper surface, wherein the lip engaged with the screw holds the screw in place in the second portion of the slot.

13. The method of claim 9 , the second upper surface is recessed into the ramp body relative to the first upper surface.

14. A system comprising:
a screw comprising a screw head;
a slide-in ramp, the slide-in ramp including
a ramp body,
a head load/unload section connected to the ramp body,
a slot defined in the ramp body, the slot including a first portion and a second portion, a first upper surface of the ramp body surrounding the first portion of the slot at a top side of the ramp body, a second upper surface of the ramp body surrounding the second portion of the slot at the top side of the ramp body, the screw positioned in the slot, and
a lip defined between the first upper surface and the second upper surface, the lip shaped complimentary to a radius of curvature of the screw head, the lip engaging the screw head and securing the slide-in ramp relative to the screw when the screw is installed in the second portion of the slot.

15. The system of claim 14 , wherein:
in a pre-installed position, the screw is positioned in the first portion of the slot proximate to a front end of the slot; and
in an installed position, the screw is positioned in the second portion of the slot proximate to a back end of the slot.

16. The system of claim 15 , wherein the lip extends from a side of the slot to an end of the ramp body, and wherein in the installed position, a screw head of the screw is engaged with the lip such that the lip holds the screw in place in the second portion of the slot in the installed position.

17. The system of claim 15 , wherein the lip extends from a first side of the slot to a second side of the slot, wherein the first upper surface surrounds the second upper surface, and wherein in the installed position, a screw head of the screw is engaged with the lip at the first side of the slot and at the second side of the slot such that the lip holds the screw in place in the second portion of the slot in the installed position.

18. The system of claim 14 , wherein in the installed position, a portion of the screw head is positioned below the first upper surface of the ramp body.

19. The system of claim 14 , wherein the second upper surface is recessed into the ramp body relative to the first upper surface.
