ABSTRACT:
A positioner which can move an object such as a magnetic recording head. The positioner includes a housing with an inner opening. The housing is located within a coordinate system that includes an x axis, a y axis and a z axis. An electrical/mechanical transducer is coupled to the inner opening of the housing by at least two flexure joint inserts. Expansion or contraction of the transducer creates a movement of the housing along the x or y axis. The flexure joint inserts allow the transducer to be adjusted within the inner opening during assembly to minimize the out of plane movement of the housing along the z axis.
