A method for forming an inductor device. The method comprises forming a trench within a central core region of a conductive coil formed within a dielectric material. The method further comprises forming a composite region within the trench. The composite region including a polymer matrix having a plurality of particles with magnetic properties dispersed therein with the central core region to reduce eddy current loss and increase energy storage.

Methods of assembling motor windings comprising wrapping windings around a central longitudinal axis in a cylindrical shape having a plurality of annularly spaced positions such that the windings form n and/or u shapes around the positions. As the windings encircle the longitudinal axis, they are wrapped in an outward spiral or inward spiral such that each pass of the windings is stacked on a previous pass.

A method provides a magnetic write apparatus. The method includes providing a pole including a pole tip, a yoke, a pole bottom and a pole top. The pole is seam free and formed vertically in a direction from the pole bottom toward the pole top. At least one coil for energizing the pole is also provided. In some aspects, providing the pole may include removing a portion of an intermediate layer to form a trench therein. The trench has a shape and location corresponding to the pole, a bottom, a top and sides. A conductive layer is deposited in the trench and on a top surface of the intermediate layer. Insulating layer(s) are provided on the sides of the trench. Only part of the conductive layer on the trench bottom is exposed. Pole material(s) are grown on the exposed portion of the conductive layer to provide the pole.

Various embodiments includes a stacked open pattern inductor fabricated above a semiconductor substrate. The stacked open pattern inductor includes a plurality of parallel open conducting patterns embedded in a magnetic oxide or in an insulator and a magnetic material. A layer of magnetic material may be located above the inductor and below the inductor to confine electronic noise generated in the stacked open pattern inductor to the area occupied by the inductor. The stacked open pattern inductor may include a magnetic material directly contacts one of the conducting patterns and the substrate. The stacked open pattern inductor may be fabricated using conventional integrated circuit manufacturing processes, and the inductor may be used in connection with computer systems.

An electrically conductive spring having first and second coils defining first and second electrical pathways for completing an electric circuit between two components which may move relative to each other. In one embodiment, the spring is a double start helical spring with first and second coils extending between respective, electrically insulated ends with the coils extending in alternating, spaced relation to each other.
