摘要:
An electrochromic device with high transmittance is for use as a display device. The electrochromic device includes at least a first and a second electrode formed on an insulative substrate and a conductive layer formed in contact with the insulative substrate, the first electrode, and the second electrode. Since an electrode layer functions in one layer, the transmittance through the device is enhanced, and the device can be fabricated in a simple process, allowing a reduction in the device fabrication costs.

An information recording medium and manufacturing method for high-speed and high density recording. An inorganic film is formed by sputtering while applying a bias voltage to shift the substrate voltage potential in the negative direction, or a laminated film is formed by applying energy after coating a substrate with an organic film, and the irregularities maintained even after the laminated film is formed, so that stable, high-capacity and high-speed recording can be attained by forming a multi-information-layer that still retains the irregularities.

Disclosed herewith is a method for enabling fast and high density recording of information. A voltage is applied to a recording layer formed between a pair of electrodes. The distance between the pair of electrodes is set wider at one of land and groove areas of a subject optical disk and narrower at the other, or the disk has multi-recording layer structure and light absorption occurs only in the layer on which coloring voltage is applied. The optical disk is provided with a layer of which light absorption spectrum changes according to the application of voltage, thereby absorbing the light. The layer may be the recording layer itself or a layer adjacent to the recording layer. Because a heat generates only in a selected area of the optical disk at the time of recording, the disk can also avoid cross-talks between layers during reading and can be turned rapidly and permissively to the auto focusing and tracking offsets, thereby enabling fast and high density recording. The disk can thus be formed with easily selectable multiple layers.

The optical disk is also provided with a layer of which light absorption spectrum changes according to the application of an electric current, thereby absorbing the light. The new layer may be the recording layer itself or a layer adjacent to the recording layer. Because a heat generates only from a small area of the optical disk at the time of recording, the disk can be turned rapidly and permissively to the auto focusing and tracking offsets, thereby enabling fast and high density recording.

摘要:
An information recording method and information recording apparatus is capable of resolving the trade-off relation between recording density and transmittance, wherein either the reproduction (playback) signal quality or the recording sensitivity is lowered. For this purpose, a voltage is applied by way of ball bearings or slip rings to a specified layer of a medium having multiple layers. The light transmittance of the recording layer is changed by application of this voltage. The tradeoff relationship between recording density and transmittance is eliminated thereby, and the recording density and transmittance levels are both improved, so as to enhance the recording reliability.

The present invention relates to an information-recording medium for recording and reproducing information by using light and a method for recording information for the purpose of high-speed and high-density recording. The medium has a structural unit having a conductive polymer layer and an electrolyte layer sandwiched by a pair of electrode layers, each of which contains a thermally decomposable or crosslinkable compound. The medium described above allows high-speed rotation of the medium as it has a narrower range heated during recording and is more tolerant of displacement of auto-focusing or tracking, and also allows high-speed and high-density recording. The medium also allows lamination of multiple layers and easier selection of layers therein.
