    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： An apparatus and method is provided for uniformly coating a magnet having a plurality of surfaces and includes a reaction chamber having a port for introducing the magnet into the reaction chamber. A heater is also included for heating the reaction chamber. Also, a carrier gas port is in fluid communications with the reaction chamber for introducing a carrier gas into the reaction chamber. In addition, a reactant gas port is in fluid communications with the reaction chamber for introducing a reactant gas into the reaction chamber. When the magnet and the carrier gas are introduced into the reaction chamber, the magnet becomes suspended in the reaction chamber. Also, when the reactant gas is introduced into the reaction chamber, the reactant gas causes all of the plurality of surfaces of the magnet to be uniformly coated.

    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.
