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 baseplate for a disk drive suspension comprising:
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; and a swage hub at a proximal end, the proximal end is opposite the distal end; and an indented surface surrounding the swage hub, the indented surface is at least partially defined by a baseplate support section.

2 . The baseplate of claim 1 , comprising a left-side mounting region and a right-side mounting region at the distal end, each mounting region includes at least one mounting shelf extending from the base plate and configured to receive an actuator.

3 . The baseplate of claim 2 , wherein the baseplate is configured to be used with a dual stage actuated suspension.

4 . The baseplate of claim 2 , wherein an actuator mounting shelf closer to the distal end includes a mating element configured to abut the spring of the load beam.

5 . The baseplate of claim 2 , wherein each mounting region includes a section of the spring extended into the mounting region to function as a mounting shelf for the actuator.

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

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

8 . The baseplate of claim 1 , wherein the receiving space includes an etched surface configured to mate with the spring of the load beam.

9 . The baseplate of claim 1 , wherein the baseplate support section is asymmetrical.

10 . The baseplate of claim 1 , wherein the baseplate support section is symmetrical.

11 . The baseplate of claim 1 , comprising a first rail and a second rail.

12 . The baseplate of claim 11 , wherein the first rail and the second rail are formed in the baseplate and extend at least along a portion of the baseplate.

13 . The baseplate of claim 11 , wherein the first rail and the second rail are formed in the load beam and extend along at least a portion of the baseplate.

14 . The baseplate of claim 11 , wherein the first rail and the second rail each include a flange.

15 . 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; and a swage hub at a proximal end, the proximal end is opposite the distal end; and an indented surface surrounding the swage hub, the indented surface is at least partially defined by a baseplate support section.

16 . The disk drive suspension of claim 15 , comprising a left-side mounting region and a right-side mounting region at the distal end, each mounting region includes at least one mounting shelf extending from the base plate and configured to receive a actuator.

17 . The disk drive suspension of claim 16 , wherein the disk drive suspension is configured to be used with a dual stage actuated suspension.

18 . The disk drive suspension of claim 16 , wherein an actuator mounting shelf closer to the distal end includes a mating element configured to abut the spring of the load beam.

19 . The disk drive suspension of claim 16 , wherein each mounting region includes a section of the spring extended into the mounting region to function as a mounting shelf for the actuator.

20 . The disk drive suspension of claim 15 , wherein the disk drive suspension is configured to be used with a tri-stage actuated suspension.

21 . The disk drive suspension of claim 15 , wherein the indented surface is shaped to correspond with an actuator arm profile area, outlined by the baseplate support section.

22 . The disk drive suspension of claim 15 , wherein the receiving space includes an etched surface configured to mate with the spring of the load beam.

23 . The disk drive suspension of claim 15 , wherein the baseplate support section is asymmetrical.

24 . The disk drive suspension of claim 15 , wherein the baseplate support section is symmetrical.

25 . The baseplate of claim 15 , comprising a first rail and a second rail.

26 . The baseplate of claim 25 , wherein the first rail and the second rail are formed in the baseplate and extend at least along a portion of the baseplate.

27 . The baseplate of claim 25 , wherein the first rail and the second rail are formed in the load beam and extend along at least a portion of the baseplate.

28 . The baseplate of claim 25 , wherein the first rail and the second rail each include a flange.
