TL;DR: A holographic recording medium as discussed by the authors includes a holographic material layer in which information is recorded by irradiating the same region with information light corresponding to the information to be recorded and reference light to read the recorded information.

TL;DR: An optical disk recording method of recording data on an optical disk by applying laser light to a track of the optical disk, including the steps of a) driving a plurality of laser light sources in sequence in a time division manner, and applying a light flux to one track of optical disk successively.

TL;DR: In this paper, a branch metric computation unit and a plurality of parallel computation units, each of which includes path metric computation units configured to compute path metric value based on branch metric values, path metric memories operable to store the path metric values to be used in a next following path metric computations, and modified-path generators configured to generate an inverted path that is inverse to a path indicated by an output of the reliability computation units as having low reliability.

TL;DR: In this article, a wireless power transmitting device includes a housing configured to have a feeding surface on which a power receiving device is to be placed, a power transmitting coil disposed inside the housing, and an alternating-current power supply configured to supply power to the power transmission coil, wherein the feeding surface has raised and recessed portions in an area corresponding to a region inside an outer region of the power transmitting coils.

TL;DR: In this paper, a non-contact charging apparatus is configured to, using variable information for varying the inductance and the capacitance of a matching unit for matching the impedance of a power supply system associated with a combination of the first distance representing the length of a line segment connecting the position of the center point of a Power Transmitting Resonance Coil (PTR) and the position in a power transmitting resonance coil and the second distance that is the distance between the plane having the power receiving resonance coil (PWC) having the same position.
