Claims
- 1. A solid state actuation mechanism for use in a data storage system, comprising:
an anchor fixedly attached to a housing of the data storage system; a spring member having a first end coupled to the anchor; a suspension coupled to a second end of the spring member, the suspension supporting a data head above a media surface, the suspension being biased by the spring member toward a first position; and an actuator component coupled to the suspension, and configured to apply an actuation force to the suspension to move the suspension laterally relative to the media surface.
- 2. The actuation mechanism of claim 1 wherein the first end of the spring member is stationary relative to the housing.
- 3. The actuation mechanism of claim 1 wherein the spring member further comprises two arms extending from the anchor to the suspension, the two arms spaced apart from each other.
- 4. The actuation mechanism of claim 3 wherein the two arms are configured to bend laterally relative to the media surface in response to the applied actuation force.
- 5. The actuation mechanism of claim 3 wherein the two arms are configured to expand or contract independently of each other in response to the applied actuation force.
- 6. The actuation mechanism of claim 3 wherein a portion of each of the two arms extends outside a plane defined by major surfaces of the anchor and the suspension.
- 7. The actuation mechanism of claim 3 wherein the two arms are coupled to a first end of the suspension, and the data head is disposed at a second end of the suspension.
- 8. The actuation mechanism of claim 3 wherein the actuator component includes a coil attached to a side of the suspension opposite a side facing the media surface.
- 9. The actuation mechanism of claim 3 wherein the actuator component includes a magnet attached to a side of the suspension opposite a side facing the media surface.
- 10. The actuation mechanism of claim 2 wherein the spring member, anchor, and suspension are formed from a unitary piece of material
- 11. The actuation mechanism of claim 1 wherein the coupling between the spring member and the suspension is at a coupling point on a side of the suspension.
- 12. The actuation mechanism of claim 11 wherein the coupling point generally defines a pivot axis about which the suspension pivots in response to the applied actuation force.
- 13. The actuation mechanism of claim 12 wherein the coupling point is located between the actuator component and the data head.
- 14. The actuation mechanism of claim 13 wherein the actuator component is disposed at a first end of the suspension and the data head is disposed at a second end of the suspension.
- 15. The actuation mechanism of claim 1 wherein the actuator component is disposed on a portion of the anchor.
- 16. The actuation mechanism of claim 15 wherein the actuator component comprises a voice coil.
- 17. The actuation mechanism of claim 16 wherein a portion of the coil supports the suspension over the media surface.
- 18. The actuation mechanism of claim 15 wherein a portion of the actuation component comprises the spring member.
- 19. The actuation mechanism of claim 18 wherein the spring member is a coil spring.
- 20. A solid state actuator comprising:
an anchor; a spring member having a first end coupled to the anchor; a suspension coupled to a second end of the spring member, the suspension having a proximal end and a distal end; an actuation component coupled to the proximal end of the suspension; wherein the actuation component is configured to apply an actuation force to the suspension to move the suspension laterally relative to a plane defined by the anchor and the suspension; and wherein the spring member biases the suspension to a first position.
- 21. The solid state actuator of claim 20 wherein the first end of the spring member is stationary relative to the suspension.
- 22. The solid state actuator of claim 20 wherein the spring member comprises two arms extending from the anchor to the suspension, the two arms spaced apart from each other.
- 23. The solid state actuator of claim 22 wherein the actuation component includes a coil attached to the suspension.
- 24. The solid state actuator of claim 22 wherein the anchor, the spring member, and the suspension are formed from a unitary piece of material.
- 25. The solid state actuator of claim 20 wherein the coupling between the spring member and the suspension is at a coupling point on a side of the suspension located between the proximal and distal ends of the suspension.
- 26. The solid state actuator of claim 25 wherein the coupling point generally defines a pivot axis about which the suspension pivots in response to the applied actuation force.
- 27. The solid state actuator of claim 20 wherein the actuation component is disposed on a portion of the anchor.
- 28. The solid state actuator of claim 27 wherein the actuation component comprises a voice coil.
- 29. The solid state actuator of claim 28 wherein a portion of the action component comprises the spring member.
