Abstract

An improved load beam is described herein. In some embodiments, the load beam comprises a major surface including a proximal end and a distal end, the distal end including a tip weld, a dustpan, and a lift tab; side rails extending from the major surface and the dustpan; and a slit disposed on the major surface about the tip weld.

First claim

What is claimed is:

1. A load beam comprising:
a major surface including a proximal end and a distal end, the distal end including a tip weld, a dustpan, and a lift tab;
side rails extending from the major surface and the dustpan; and
a slit disposed on the major surface about the tip weld, wherein the tip weld is disposed at a dustpan forming line between the major surface and the dustpan.

2. The load beam of claim 1 , wherein a convex portion of the slit is distal to the tip weld.

3. The load beam of claim 1 , wherein a dustpan forming line is disposed through the tip weld or through the proximal end of the tip weld.

4. The load beam of claim 1 , wherein the dustpan forms an angle θ that is between 15 to 25°.

5. The load beam of claim 1 , wherein the slit is in a semicircular shape about the tip weld.

6. The load beam of claim 1 , wherein the slit is in a U-shape about the tip weld.

7. The load beam of claim 1 , wherein the dustpan includes a proximal end and a distal end, the proximal end includes the dustpan forming line, and the distal end includes a lift tab.

8. The load beam of claim 7 , wherein the lift tab is disposed distal of the dustpan.

9. The load beam of claim 1 , wherein the major surface includes a dimple.

10. The load beam of claim 1 , wherein the major surface includes a window.

11. A suspension comprising:
a load beam comprising:
a major surface including a proximal end and a distal end, the distal end including a tip weld, a dustpan, and a lift tab;
side rails extending from the major surface and the dustpan; and
a slit disposed on the major surface about the tip weld, wherein the tip weld is disposed at a dustpan forming line between the major surface and the dustpan.

12. The suspension of claim 11 , wherein a convex portion of the slit is distal to the tip weld.

13. The suspension of claim 11 , wherein the dustpan forming line is disposed through the tip weld.

14. The suspension of claim 11 , wherein the dustpan forms an angle θ that is between 15 to 25°.

15. The suspension of claim 11 , wherein the slit is in a semicircular shape about the tip weld.

16. The suspension of claim 11 , wherein the slit is in a U-shape about the tip weld.

17. The suspension of claim 11 , wherein the dustpan includes a proximal end and a distal end, the proximal end includes the dustpan forming line, and the distal end includes a lift tab.

18. The suspension of claim 17 , wherein the lift tab is disposed distal of the dustpan.

19. The suspension of claim 11 , wherein the major surface includes a dimple.

20. The suspension of claim 11 , wherein the major surface includes a window.

21. A suspension comprising:
a load beam, the load beam including a mounting region at a proximal end of the load beam and a rigid region at a distal portion of the load beam;
a base plate, the base plate mounted to the mounting region of the load beam; and
a flexure, the flexure mounted to the rigid region of the load beam, wherein the load beam further comprises:
a major surface including a proximal end and a distal end, the distal end including a tip weld, a dustpan, and a lift tab;
side rails extending from the major surface and the dustpan;
and a slit disposed on the major surface about the tip weld, wherein the tip weld is disposed at a dustpan forming line between the major surface and the dustpan.
