Structure and fabrication process for integrated moving-coil magnetic micro-actuator

A dual structure microactuator for positioning a transducing head relative to a select track of a disc, the dual structure microactuator comprising:

• a first structure having a stator and a rotor, wherein the rotor comprises a coil embedded into a surface of the rotor;
• and
• a second structure carrying a magnet and comprising mechanical stand-offs;
• wherein the first structure is attached to the second structure.

A dual structure microactuator having a stator and a rotor for finely positioning a slider above a surface of a disc, the dual structure microactuator comprising:

• a first structure comprising a coil embedded in a surface of the first structure so that the surface remains essentially planar;
• and
• a second structure comprising a magnet;
• wherein the second structure is attached to the first structure so that a gap is formed between the magnet of the second structure and the embedded coil of the first structure.
