Abstract
A head having micro-positioning control. The head includes a slider body and a transducer body coupled to the slider body through a flexible interface. The transducer body is spaced from the slider body to form a gap therebetween. Micro-positioning actuators are coupled to the transducer body in the gap to provide micro-positioning control. In an embodiment for an air bearing slider, the gap includes off-track and fly height positioning control.
Claims21
A head comprising:
- a slider body having a leading edge, a trailing edge, and an air bearing surface;
- a transducer body spaced from the trailing edge of the slider body to form a gap between the trailing edge of the slider body and the transducer body and the transducer body including at least one transducer element;
- at least one flexure body in the gap between the trailing edge of the slider body and the transducer body;
- and
- a first actuator energizable to micro-position the transducer body in a first off-track direction relative to the slider body and a second actuator energizable to micro-position the transducer body in a second direction towards or away from a data storage surface.
