Abstract

A baseplate for a disk drive suspension is provided. The baseplate includes a receiving space at a distal end configured to mate with a spring of a load beam. The receiving space partially extends a length of the baseplate. The baseplate also includes a swage hub at a proximal end and an indented surface surrounding the swage hub. The proximal end is opposite the distal end. The indented surface is at least partially defined by a baseplate support section.

First claim

What is claimed is:

1. A disk drive suspension comprising: a baseplate, the baseplate including:
a receiving space at a distal end configured to mate with a spring of a load beam, the receiving space partially extends a length of the baseplate;
a swage hub at a proximal end, the proximal end is opposite the distal end;
an indented surface surrounding the swage hub, the indented surface is at least partially defined by a baseplate support section; and
a first rail extending along a first side of the baseplate and a second rail extending along a second side of the baseplate substantially in parallel with the first rail, wherein the first rail and the second rail each include a first end terminating at the distal end of the baseplate and a second end terminating at the proximal end of the baseplate, wherein the first rail and the second rail each include a first surface extending upward away from the baseplate and a flange that comprises a surface of the first rail and the second rail that extends away from the baseplate and is perpendicular to the first surface.

2. The disk drive suspension of claim 1 , wherein the first rail and the second rail extend along the baseplate.

3. The disk drive suspension of claim 1 , wherein the first rail and the second rail are formed in the load beam.

4. The disk drive suspension of claim 1 , wherein the baseplate is configured to be used with a dual-stage actuated suspension.

5. The disk drive suspension of claim 1 , wherein the baseplate is configured to be used with a tri-stage actuated suspension.

6. The disk drive suspension of claim 1 , wherein the indented surface is shaped to correspond with an actuator arm profile area, outlined by the baseplate support section.

7. The disk drive suspension of claim 1 , wherein the receiving space includes an etched surface configured to mate with the spring of the load beam.

8. A disk drive suspension comprising:
a load beam including a spring; and
a baseplate coupled to the spring of the load beam, the baseplate including:
a receiving space at a distal end configured to mate with the spring of the load beam, the receiving space partially extends a length of the baseplate;
a swage hub at a proximal end, the proximal end is opposite the distal end;
an indented surface surrounding the swage hub, the indented surface is at least partially defined by a baseplate support section; and
a first rail extending along a first side of the baseplate and a second rail extending along a second side of the baseplate substantially in parallel with the first rail, wherein the first rail and the second rail each include a first end terminating at the distal end of the baseplate and a second end terminating at the proximal end of the baseplate, wherein the first rail and the second rail are formed in the load beam and each include a first surface extending upward away from the baseplate and a flange that comprises a surface of the first rail and the second rail that extends away from the baseplate and is perpendicular to the first surface.

9. The disk drive suspension of claim 8 , wherein the first rail and the second rail extend along the baseplate.

10. The disk drive suspension of claim 8 , wherein the disk drive suspension is configured to be used with a dual-stage actuated suspension.

11. The disk drive suspension of claim 8 , wherein the disk drive suspension is configured to be used with a tri-stage actuated suspension.

12. The disk drive suspension of claim 8 , wherein the indented surface is shaped to correspond with an actuator arm profile area, outlined by the baseplate support section.

13. The disk drive suspension of claim 8 , wherein the receiving space includes an etched surface configured to mate with the spring of the load beam.
