Abstract
This invention relates to a method for manufacturing a head positioning apparatus for a data storage system and a head positioning apparatus made by the above method, which removes the slider from being a movable part in the second stage of the head positioning operation. By integrately forming an electrostatic microactuator between the slider and the read/write heads, a aspect ratio higher than 100:4 is achieved without using the high cost process such as the X-ray exposing process. In addition, the weight of the second stage movable parts are reduced therefore the servo control bandwidth may be increased and a track density higher than 100 kTPI can be achieved.
