Active fiber composite data storage device suspension
A data storage device may employ a suspension that positions a transducing head proximal a data storage medium. The suspension can consist of an active fiber composite that spans a portion of a loadbeam. The active fiber composite can be configured with at least one active fiber contacting a supporting layer.
1. An apparatus comprising a data storage device having a suspension positioning a transducing head proximal a data storage medium, the suspension comprising an active fiber composite spanning a portion of a loadbeam, the active fiber composite comprising a first active fiber contacting, and separated from a second active fiber of the active fiber composite by, a non-conductive supporting layer, the first active fiber and second active fiber each separated from an electrode of the active fiber composite by the supporting layer.
2. The apparatus of claim 1 , wherein the non-conductive supporting layer surrounds the first active fiber.
3. The apparatus of claim 1 , wherein the active fiber composite continuously contacts a top surface of the loadbeam, the top surface opposite a bottom surface that contacts a gimbal, the gimbal supporting the transducing head.
4. The apparatus of claim 1 , wherein the first active fiber comprises a piezoelectric transducer material.
5. The apparatus of claim 1 , wherein the first active fiber has a longitudinal axis aligned parallel with a longitudinal axis of the active fiber composite.
6. The apparatus of claim 1 , wherein the active fiber composite has a greater thickness than the loadbeam.
7. The apparatus of claim 1 , wherein the loadbeam is connected to a baseplate via at least one microactuator.
8. An apparatus comprising a data storage device having a suspension positioning a transducing head proximal a data storage medium, the suspension comprising an active fiber composite spanning a portion of a loadbeam, the active fiber composite comprising a first and second active fibers suspended between a first electrode and a second electrode, the first active fiber separated from the second active fiber by contacting a supporting layer, the first and second active fibers each separated from the first and second electrodes by the supporting layer.
9. The apparatus of claim 8 , wherein the first and second electrodes are respectively positioned on separate surfaces of the active fiber composite.
10. The apparatus of claim 8 , wherein the first electrode is separated from a third electrode on a common surface of the active fiber composite.
11. The apparatus of claim 8 , wherein the first and second electrodes are electrically independent and connected to different ports of a controller.
12. The apparatus of claim 8 , wherein the first and second active fibers are each electrically conductive and selectable.
13. The apparatus of claim 8 , wherein the first electrode comprises a positive lead and a negative lead.
14. The apparatus of claim 13 , wherein the positive lead of the first electrode comprises at least one positive finger separated from at least one negative finger on a common surface of the active fiber composite.
15. The apparatus of claim 8 , wherein the active fiber composite spans an aperture in the loadbeam.
16. A method comprising:
positioning a transducing head proximal a data storage medium with a suspension of a data storage device, the suspension comprising an active fiber composite spanning a portion of a loadbeam, the active fiber composite comprising a first active fiber and a second active fiber, the first active fiber physically separated from the second active fiber, each active fiber contacting a non-conductive supporting layer, each active fiber separated from an electrode of the active fiber composite by the supporting layer;
activating at least one electrode of the active fiber composite to manipulate a position of the transducing head relative to the data storage medium; and
sensing a position of the suspension with the active fiber composite while the at least one electrode is activated.
17. The method of claim 16 , wherein the transducing head is manipulated to decrease an air bearing size between the transducing head and the data storage medium.
18. The method of claim 16 , wherein the transducing head is manipulated to rotate the loadbeam and move the transducing head from a first track of the data storage medium to a different second track of the data storage medium.
19. The method of claim 16 , wherein motion of the transducing head is sensed by a controller via signals received from the active fiber composite.
