摘要： A moving-coil magnetic microactuator is formed by using a dual silicon wafer structure and thin film technologies such as deep trench reactive ion etching, reactive ion etching, plasma-enhanced chemical vapor deposition and metallo-organinc chemical vapor deposition. Several bottom structures are formed from a bottom wafer, each bottom structure having a coil and wires embedded in the surface of the bottom structure. Several top structures are formed from a top wafer, each top structure having a magnet and mechanical stand-offs. The top structures are bonded to the bottom structures so that the magnet is above the embedded coil, separated by an air gap created by the mechanical stand-offs.

摘要： A method of fabricating a disc drive actuation system having a head level magnetic micro-actuation assembly utilizing flexible beam inserts and the disc drive actuation system thereby produced are provided. The method comprises the steps of: (a) forming a mold with a first cavity for a micro-actuator body and a second cavity for a slider body; (b) placing a plurality of magnets in a magnet keeper; (c) placing the magnet keeper in the second cavity of the mold; (d) etching a flexible beam insert from a flexible material such as sheet stainless steel; (e) placing the flexible beam insert into the mold, (f) filling the mold with a fluid; (g) solidifying the fluid to form the micro-actuator body and the slider body; (h) removing the micro-actuator body and slider body from the mold; and (i) inserting a slider into the slider body, thereby forming the magnetic micro-actuator assembly; and (j) installing the magnetic micro-actuator assembly into a disc drive assembly, and thereby producing the disc drive actuation system having a head level magnetic micro-actuator assembly utilizing flexible beam inserts. This fabrication process involves a single injection-molding step, a tremendous cost and fabrication advantage over conventional MEMS processing. The resultant disc drive actuation system has a magnetic micro-actuator assembly which is an injection-molded micro-actuator body and an injection-molded slider body, having flexible beams metal inserts extending from the micro-actuator body to the slider body. The slider body supports a slider with a transducing head. The micro-actuator body acts as a stator of a motor and the slider body acts as a rotor of a motor. The flexible beams allow movement between the micro-actuator body and the slider body. The movement of the slider body allows for a finer movement of the transducing head over a disc seated in a disc drive.
