摘要： An apparatus for reproducing information from records made by an optical-wavelength-multiplexing method which includes a first medium acting as a data carrier which data can be recorded on and reproduced from by the optical-wavelength-multiplexing method and which further includes a second medium having the same characteristic as that of the first medium on which no records have been made, wherein components of light reflected or transmitted by the first and second mediums are then detected by a first and second photodetectors, respectively, and wherein the outputs of the first and second photodetectors are further processed so that a ground level of the "reproduced signal" is adjusted to substantially constant value.

摘要： The storage medium 30 for an optical data storage system is a contiguous laminate formed by a plurality of layers 18, 19, 20 of photochemical hole burning material, such layers individually exhibiting inhomogenous absorption spectrum characteristics spanning different, successive wavelength ranges. This arrangement greatly expands the cumulative or overall absorption band of the storage medium available for laser hole burning to implement data bit writing, and thus increases the storage density at each memory site. The absorption spectrum characteristics of the layers can be varied by including coloring dyes in the layers.

摘要： An optical information carrier comprises a cylinder (1) with a recording layer (2) inside it, as well as bushings (3, 4) mounted on the butt-ends of the cylinder (1) and isolating the recording layer (2) from the outside space. A method of erasing information recorded on said optical carrier consists in the excitation of a high-frequency electrical charge inside a sealed closed cavity (5) of the cylinder (1). An optical memorization device for implementation of said method has an information erasing unit (11) comprising a high frequency charge excitation circuit with electrodes (12, 13), between which an optical information carrier (10) is placed in order to excitate a high-frequency charge inside its sealed closed cavity (5).

摘要： Disclosed is a rewritable information recording medium which has a recording layer (2) containing a Group I transition element and a Group IV typical element of the Periodic Table as two principal element and having the following characteristics, and a support substrate (1) for physically supporting the recording layer (2), and an information-write, -read, and -erase method, using this recording medium. When the recording layer (2) is immediately cooled after it is heated up to near a eutetic temperature of the two principal elements, two metastable phases having different energy levels appear. A state in the first metastable phase of the higher energy level has a reflectivity sufficiently higher than that of a state of a mixed phase including the second metastable phase of the lower energy level, or that of the equilibrium state. The state in the first metastable phase can be obtained by heating a recording layer (2) in another state by light beam irradiation. A portion (3) in the first metastable state is cooled after it is heated to a temperature lower than that for obtaining the first metastable phase, so that it can be converted to a state of the low reflectivity, i.e., a state of a mixed phase including the second metastable phase or to the equilibrium state. Since the recording layer can be reversibly altered between states of high and low reflectivities upon light beam irradiation, information can be erasably written. A write or erase-operation can be performed in a short period of time dur to the relationship between the crystal structures of the two states. Furthermore, the medium of this invention has no toxicity in terms of its constituents, and has good environmental resistance.
