Abstract

Implementation of a non-interfering micro-positioning device, for a tape drive write/read head module assembly utilizing piezoelectric elements, by generating at least two flexure brackets. The at least two flexure brackets may include the piezoelectric elements. Affixing at least one flexure bracket to a first side of the write/read head module assembly. Affixing at least one other flexure bracket to a second side of the write/read head module assembly.

Claims (25)

1. A method for implementing a non-interfering micro-positioning device for a tape drive write/read head module assembly utilizing piezoelectric elements, the method comprising:

generating at least two flexure brackets, wherein each flexure bracket includes at least one piezoelectric element attached thereto;

affixing at least one of the flexure brackets to a first side of the write/read head module assembly; and

affixing at least another one of the flexure brackets to a second side of the write/read head module assembly;

wherein after the affixing of the flexure brackets to the write/read head module assembly, each piezoelectric element has a longitudinal orientation that generally corresponds to a longitudinal orientation of the write/read head module assembly.

2. The method of claim 1 , wherein the at least two flexures include a flexure for each of a top portion and a bottom portion of the first side of the write/read head module assembly and the second side of the write/read head module assembly.

3. The method of claim 1 , wherein the write/read head module assembly includes one or more head cables and a mechanical ground module for the at least two flexures to shift on.

4. The method of claim 1 , further comprising:

energizing the at least two flexure brackets in order to shift the write/read head module assembly in a particular direction.

5. The method of claim 4 , wherein shifting the write/read head module assembly in the particular direction is done in a corresponding direction as a placement of the mechanical ground.

6. The method of claim 4 , wherein energizing the at least two flexure brackets in order to shift the write/read head module assembly in the particular direction includes energizing the piezoelectric elements of the at least two flexure brackets in concert.

7. The method of claim 6 , wherein energizing the at least two flexure brackets in concert causes the expansion of the at least two flexure brackets.

8. The method of claim 6 , wherein energizing the at least two flexure brackets concert causes the contraction of the at least two flexure brackets.

9. A non-interfering micro-positioning system for a tape drive write/read head module assembly utilizing piezoelectric elements, the system comprising:

at least two flexure brackets, wherein each flexure bracket includes at least one piezoelectric element attached thereto;

at least one of the flexure brackets affixed to a first side of the read/write head module assembly; and

at least another one of the flexure brackets affixed to a second side of the write/read head module assembly;

wherein each piezoelectric element has a longitudinal orientation that generally corresponds to a longitudinal orientation of the write/read head module assembly.

10. The system of claim 9 , wherein the at least two flexures include a flexure for each of a top portion and a bottom portion of the first side of the write/read head module assembly and the second side of the write/read head module assembly.

11. The system of claim 9 , wherein the write/read head module assembly includes one or more head cables and a mechanical ground module for the at least two flexures to shift on.

12. The system of claim 9 , wherein the at least two flexure brackets are energized in order to shift the write/read head module assembly in a particular direction.

13. The system of claim 12 , wherein shifting the write/read head module assembly in the particular direction is done in a corresponding direction as a placement of the mechanical ground.

14. The system of claim 12 , wherein energizing the at least two flexure brackets in order to shift the write/read head module assembly in the particular direction includes energizing the piezoelectric elements of the at least two flexure brackets in concert.

15. The system of claim 14 , wherein energizing the at least two flexure brackets in concert causes the expansion of the at least two flexure brackets.

16. The system of claim 14 , wherein energizing the at least two flexure brackets in concert causes the contraction of the at least two flexure brackets.
