摘要： High-speed and high-density recording of a layer-selected optical disc are enabled with a small number of electrodes. A plurality of recording films that are independently selectable are disposed between a pair of electrodes 3 and 8. The recording films are controlled individually in terms of a threshold of voltage required for coloration and electric characteristics. A desired layer can be selected by changing the voltage applied between the pair of electrodes.

摘要： In the past there has been a problem that on a detection surface the influence of interference causes a defocusing signal to degrade, narrowing the range in which spherical aberration can be stably detected. Accordingly, a diffraction grating is used to focus the inner and outer sides of luminous flux on separate optical detectors before the optical flux is focused on an optical detector and defocusing signals are independently calculated to find the difference therebetween, thereby providing a spherical aberration signal. This makes it possible to detect spherical aberration signals more stably.

摘要： An information recording method in which an energy beam is irradiated to a recording medium and a basic recording pattern is generated. The basic recording pattern has a first power level provides a first state and a second power level providing a second state. Based upon a period of a recording timing generating clock in a recording mode, and a relative velocity of the energy beam and the recording medium, there is formed a first sequence of the second state and the first state based upon parameters as a first small recording pattern, a second sequence which starts with the first state and ends with the first state as a second small recording pattern, a state in which the second small recording pattern follows said the small recording pattern as the basic recording pattern, and a state in which the basic recording patterns are repeated as a recording pattern.

摘要： The present invention includes a panel on which a plurality of pixels are located, a light-source for visualizing an image displayed on the plurality of pixels, a controlling circuit for controlling the light-source, and an image-signal tone characteristic controlling circuit. Moreover, the light-source controlling circuit has a function of repeating a period. Here, the period includes a 1st time-period during which an electric current having a 1st intensity is fed to the light-source, and a 2nd time-period during which an electric current having a 2nd intensity differing from the 1st intensity is fed to the light-source. The light-source controlling circuit controls the 1st time-period and the 2nd time-period in accordance with display information. Also, in accordance with the display information as well, the tone characteristic controlling circuit is controlled so that the excellent contrast will be always available.
