Abstract: PROBLEM TO BE SOLVED: To increase manufacturing efficiency and thereby reduce cost of a multi-layered optical disk recording medium.SOLUTION: A film laminate (multi-layered recordable structure) is manufactured by winding multiple times and punching a film at a rewind core portion. By manufacturing the multi-layered recordable structure by winding and punching, n units of the multi-layered recordable structure may be manufactured at a time corresponding to the number n of surfaces (punching surfaces) disposed at the rewind core portion. Therefore, manufacturing efficiency for the multi-layered optical disk recording medium may increase compared to conventional manufacturing methods.

Abstract: PROBLEM TO BE SOLVED: To correctly reproduce information to be essentially recorded.SOLUTION: In an optical information reproducing device, a detection signal S obtained on the basis of a reflected light beam from an optical information recording medium is compared with a first signal level V1 and a second signal level V2 by a fluctuation detection part of a signal processing part to generate a first detection signal SV1 and a second detection signal SV2. In the signal processing part, the first detection signal SV1 and the second detection signal SV2 are converted into a first code sequence CV1 and a second code sequence CV2, respectively, by a code sequence generating part and when the second code sequence CV2 becomes a value 1, a substitution code sequence CR is substituted for a code sequence CB in the vicinity of the first code sequence CV1 to form a code sequence C. Thereby, in the optical information reproducing device, the code sequence C corresponding to two recording marks which should be essentially recorded can be generated even when merged recording marks are formed in the optical information recording medium.

Abstract: PROBLEM TO BE SOLVED: To make it possible to easily and inexpensively produce a good liquid crystal element in a short required time and to deal with a trend toward a larger area by disposing the liquid crystals in the spacing between a pair of substrates by application thereof onto a liquid crystal orientation control layer. SOLUTION: ITO transparent electrodes and liquid crystal oriented film are formed on the one substrate 22a and the substrate 22a is placed and fixed onto a turn table 12 by directing its surface formed with the transparent electrodes, etc., upward in the process of producing the ferroelectric liquid crystal display element. The liquid crystals 26 are dropped in the form of a soln. 14 dissolved in a solvent onto the substrate 22a. The liquid crystals 14 are diffused and applied, instantaneously when supplied, over the entire surface of the substrate 22a by the centrifugal force generated by rotation of the table 12. Since the solvent is of a quick dry type, the solvent is required to be applied over the entire surface before the solvent dries and, therefore, a spin coating system is more adequate. The display having a high contrast and excellent analog gradation is obtd. by incorporating particulates into the liquid crystals 26 and such display is obtd. by providing the display with the liquid crystals 26 by application.

Abstract: PURPOSE: To record a signal having high modulation factor when blue laser beam is used as a recording light and a reproduced light by forming a recording layer by porphyrin compound as a main body. CONSTITUTION: An optical recording medium comprises a recording layer 2 containing organic dye as a main body on a board 1, a reflecting layer 3 sequentially formed, and further a protective layer 4 formed thereon. The layer 2 is formed to contain porphyrin compound represented by a formula as a main body, wherein M is any of Pb, BiO, ReO, XY is O-, NO2 , Cl, Br, I, ClO4 , and BF4 . When the layer 2 is converged with a laser beam, the organic dye of the part optically absorbs to write a pit. The pit is detected by the difference of the reflectivities of the part formed with the pit and the part not formed with the pit.

Abstract: PURPOSE:To obtain an optical recording medium capable of obtaining a reproduction signal high in C/N ratio from the recording pattern of a pit formed at a cycle shorter than the diffraction limit of a reproduction optical system by recording a data signal on the saturable absorbing dye-containing layer formed on a permeable substrate by the change of an attenuation coefficient. CONSTITUTION:In an optical recording medium irradiated with reproduction light on the substrate side thereof and reproducing a signal by detecting the change of the quantity of the reflected light thereof, a high refractive layer 2, a saturable absorbing dyecontaining layer 3 and a reflecting layer 4 are successively formed on a permeable substrate. A pit 5 is formed in the pattern corresponding to a data signal by changing the attenuation coefficient (being the coefficient of the false part of a double refractive index and showing the degree of light absorption) of the saturable absorbing dye-containing layer 3. As the saturable absorbing dye contained in the saturable absorbing dye- containing layer 3, a naphthalocyanine derivative is used and the attenuation coefficient is changed by a photo-bleaching method to record a data signal.

Abstract: PROBLEM TO BE SOLVED: To prevent recorded data from being taken into a computer by disabling the reading in the high-speed reproduction, and to protect the copyright. SOLUTION: The films of transparent dielectric film 11 (Si 3 N 4 , the thickness of equal to 10 nm)/phase change film 12 (Ge 2 Sb 2 Te 5 , 10 nm)/transparent dielectric film 13 (Si 3 N 4 , 130 nm)/metal reflective film 2' (Ag, 60 nm) are deposited on a substrate 1. The film 12 is not deposited on the inner circumferential side, and the metal reflective film 2' is exposed. The film 12 as deposited is in an amorphous state, and is changed from the amorphous state to a crystalline state by an initialization process. The reflectance of the film 12 in the crystalline state is lower than that in the amorphous state. In the reproduction at one-fold velocity, the amorphous phase is generated by the thermal energy of a laser beam to increase the reflectance, and the reproduction can be performed. In the CD-ROM device, the amorphous phase is not generated due to the high-speed rotation, and the reflectance remains low. Therefore, the reproduction cannot be performed. COPYRIGHT: (C)2003,JPO
