    摘要: An antenna comprises an arrangement of electrically conducting segments, the arrangement including intersection points where two or more electrically conducting segments are in electrical communication. Example antennas include a plurality of capacitors located within some or all of the electrically conducting segments. Capacitance values can be determined using an optimization algorithm to obtain desired values of antenna resonance frequency (or frequencies), bandwidth, and/or radiation pattern, and may be adjusted in order to control an antenna parameter such as beam steering direction.

    摘要: The hard disk drive of the present invention includes a magnetic head wherein the read head portions have gap insulation layers between the magnetic shields. The gap insulation layers are made up of multilayered laminations of an oxide or nitride of a metal such as aluminum, silicon, chromium, and tantalum. A preferred embodiment of the present invention includes laminated G1 and G2 gap insulation layers having 5-10 laminations, and having a total thickness of approximately 50 Å to 500 Å.
