Abstract
A system and method for improving piezoelectric micro-actuator operation by preventing undesired micro-actuator motion hindrance and by preventing micro-actuator misalignment during manufacture.
Claims30
A system comprising:
- a shim element interposed between an electric circuit assembly and a lower portion of an actuator frame, wherein
- said electric circuit assembly has a generally ‘O’-shaped portion configured such that an upper portion of said actuator frame is able to protrude through said ‘O’-shaped portion;
- and
- said electric circuit assembly is coupled to said shim element and said shim element is to be coupled to said lower portion.
1 more element
A system for a hard disk drive comprising:
- an electric circuit assembly having a generally ‘O’-shaped portion, wherein
- said ‘O’-shaped portion is configured such that an upper portion of an actuator frame is able to protrude through said ‘O’-shaped portion;
- said electric circuit assembly is coupled to a shim element and said shim element is coupled to a lower portion of said actuator frame;
- and
- said shim element is interposed between said electric circuit assembly and said lower portion.
2 more elements
A method for manufacturing a system in a hard disk drive comprising:
- providing an electric circuit assembly having a generally ‘O’-shaped portion configured such that an upper portion of an actuator frame protrudes through said ‘O’-shaped portion;
- and
- coupling said electric circuit assembly to a shim element and said shim element to a lower portion of said actuator frame such that said shim element is interposed between said electric circuit assembly and said lower portion.
