ABSTRACT:
A micro-actuator, its manufacturing method, an optical pickup head of an optical recording/reproducing apparatus having the micro-actuator, and its manufacturing method are disclosed. A low voltage and low power bi-directional driving is accomplished so that a size and a weight of a system can be considerably reduced and a response speed can be improved. A uniformity and a production efficiency are heightened by reducing a alignment tolerance. In addition, a configuration tolerance caused due to an uneven thickness of a protection layer of the record layer on the disk and an uneven smoothness of the disk is corrected, so that a focal point of an objective lens can be optimally made on a record layer of the disk.
