Abstract

A first semi-flexible structure and a second semi-flexible structure may be generated. The first semi-flexible structure may be bonded to a first end of a write/read tape head. The second semi-flexible structure may be bonded to a second end of the write/read tape head. A voice coil motor may be activated.

Claims (24)

1. A method for utilizing a semi-flexible linkage device for micro-positioning a write/read tape head, the method comprising:

generating a first semi-flexible structure and a second semi-flexible structure, wherein both the first semi-flexible structure and the second semi-flexible structure are J-shaped, wherein the J-shape is a curved shape with two opposite sides, wherein a first side of the J-shape has a lower height than a second side of the J-shape;

bonding the first semi-flexible structure to a first end of the write/read tape head;

bonding the second semi-flexible structure to a second end of the write/read tape head; and

activating a voice coil motor assembly.

2. The method of claim 1 , wherein the second side of the first semi-flexible structure is bonded to the first end of the write/read tape head, and wherein the second side of the second semi-flexible structure is bonded to the second end of the write/read tape head.

3. The method of claim 2 , wherein both the first semi-flexible structure and the second semi-flexible structure include a bonded piezoelectric stack.

4. The method of claim 3 , wherein the bonded piezoelectric stack in both the first semi-flexible structure and the second semi-flexible structure is located between the first side of the J-shape and the second side of the J-shape.

5. The method of claim 4 , wherein the bonded piezoelectric stack is positioned to have a top portion flush with an end portion of the first side of the J-shape, and wherein the bonded piezoelectric stack extends directly across from the first side of the J-shape to a corresponding internal portion of the second side of the J-shape.

6. The method of claim 1 , wherein activating the voice coil motor assembly causes the first semi-flexible structure and the second semi-flexible structure to move, in unison, in a same direction.

7. The method of claim 6 , further comprising:

activating a piezoelectric stack of both the first semi-flexible structure and the second semi-flexible structure, wherein activating the piezoelectric stacks amplifies the motion of the write/read head.

8. A semi-flexible linkage system for micro-positioning a write/read tape head, the system comprising:

a first semi-flexible structure, wherein the first semi-flexible structure is bonded to a first end of the write/read tape head;

a second semi-flexible structure, wherein the second semi-flexible structure is bonded to a second end of the write/read tape head, wherein both the first semi-flexible structure and the second semi-flexible structure are J-shaped, wherein the J-shape is a curved shape with two opposite sides, wherein a first side of the J-shape has a lower height than a second side of the J-shape; and

a voice coil motor assembly.

9. The system of claim 8 , wherein the second side of the first semi-flexible structure is bonded to the first end of the write/read tape head, and wherein the second side of the second semi-flexible structure is bonded to the second end of the write/read tape head.

10. The system of claim 9 , wherein both the first semi-flexible structure and the second semi-flexible structure include a bonded piezoelectric stack.

11. The system of claim 10 , wherein the bonded piezoelectric stack in both the first semi-flexible structure and the second semi-flexible structure is located between the first side of the J-shape and the second side of the J-shape.

12. The system of claim 11 , wherein the bonded piezoelectric stack is positioned to be have a top portion flush with an end portion of the first side of the J-shape, and wherein the bonded piezoelectric stack extends directly across from the first side of the J-shape to a corresponding internal portion of the second side of the J-shape.

13. The system of claim 8 , wherein the voice coil motor assembly, upon activation, causes the first semi-flexible structure and the second semi-flexible structure to move, in unison, in a same direction.

14. The system of claim 13 , further comprising:

a piezoelectric stack of the first semi-flexible structure; and

a piezoelectric stack of the second semi-flexible structure, wherein activating the piezoelectric stack of both the first semi-flexible structure and the second semi-flexible structure amplifies the motion of the write/read head.
