摘要： A magnetic recording element has a substrate, a main pole for recording that includes an edge part positioned on an air bearing surface (ABS), a waveguide through which a laser light propagates, and a plasmon generator. The plasmon generator is positioned away from the substrate and extends to the ABS as facing a part of the waveguide. The plasmon generator has a propagation edge extending in a longitudinal direction. The propagation edge has an overlapping part overlapping the waveguide in the longitudinal direction, and a near field light generator positioned on the ABS and located in the vicinity of the edge part of the recording magnetic pole. The overlapping part of the propagation edge is coupled with the laser light propagating through the waveguide in a surface plasmon mode so that a surface plasmon is generated. The propagation edge propagates the surface plasmon generated in the overlapping part to the near field light generator. The magnetic recording element further has a grounding element electrically connecting the plasmon generator and the substrate.

摘要： A wireless communication apparatus is made up of a transmission circuit block including an antenna that is laid out such that the transmission lines, i.e., the sum of the distance connecting respective circuit blocks between an output terminal of the transmission power amplifier to an input/output terminal of the antenna is shorter than the transmission line, i.e., the sum of the distance connecting respective circuit blocks between an input terminal of a transmission power amplifier and an output terminal of a RFIC disposed at a preceding stage of the transmission power amplifier. This arrangement realizes a wireless communications apparatus ensuring improvement of overall performance of the wireless application without reducing the total transmission loss or improving the performance of individual circuits.
