    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 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 composite head-electrical conditioner assembly that includes a slider with a transducer head and transducer bond pads. The transducer bond pads communicate a transducer level electrical signal with the transducer head. An integrated circuit substrate has a conditioning circuit and first substrate bond pads electrically connected to the transducer bond pads. The integrated circuit substrate has second substrate bond pads with a conditioned electrical signal that is transmittable over a circuit. The slider is rigidly mounted to the integrated circuit substrate to form an assembly that is flexibly mountable. A thermal isolation space is provided between the transducer and the conditioning circuit. The integrated circuit can be in the form of a cap that provides windage reduction.

    摘要： An apparatus and method of machining sliders to obtain the optimum PTR for each slider. An array of MEMS devices configured for angular actuation are provided, and a slider is placed in each MEMS device of the array. The ion milling of the sliders is controlled individually for each slider based on the relationship of the ion angle and relative etch rates of the slider components. The MEMS devices are controlled to ensure the ion incidence angle for each slider is such that the desired PTR of each slider is achieved.
