摘要： A description is given of a rewritable optical information medium having a phase-change recording layer (3) on the basis of an alloy of Ge-Sb-Te-O, having the composition (GeaSbbTec)1-dOd, wherein: a+b+c=1 0.0001≤d≤0.035. The addition of oxygen considerably speeds up the crystallization rate of Ge-Sb-Te materials. Such a medium is suitable for high speed recording (i.e. at least eight times the CD-speed), such as for DVD-RAM and optical tape. The amount of oxygen in the recording layer (3) can be used to tune the crystallization rate to the desired value.

摘要： When a wavelength of a first laser beam with which a first recording medium including a first recording layer is recorded and reproduced is indicated as λ1 (nm), a wavelength of a second laser beam with which a second recording medium including a second recording layer is recorded and reproduced as λ2 (nm), the relationship between the wavelength λ1 and the wavelength λ2 is set to be expressed by 10 ≦ |λ1 - λ2| ≦ 120. The first recording layer has a light absorptance ratio of at least 1.0 with respect to the wavelength λ1. The light transmittance of the first recording medium with respect to the wavelength λ2 is set to be at least 30 in both the cases where the recording layer is in a crystal state and in an amorphous state. In order to record and reproduce the optical multilayer disk with the above-mentioned characteristics, a multiwavelength light source with the following configuration is used. Wavelengths of fundamental waves with different wavelengths from injection parts formed at one end of a plurality of optical waveguides, which satisfy phase matching conditions different from one another and are formed in the vicinity of the surface of a substrate, are converted simultaneously, and the first and second laser beams are emitted from emission parts formed at substantially the same position at the other end of the optical waveguides. This enables an optimum optical system for high density recording and reproduction to be obtained.

摘要： In an optical recording medium comprising a grooved light-transparent substrate, a phase change recording layer, a dielectric layer and a reflective layer, recording is carried out by irradiating a laser beam to the recording layer through an objective lens in an optical system. The recording is carried out in the grooves under the conditions: 0.48 ≤ P T /(λ/NA) ≤ 0.74, and P T ≤ 0.50 µm wherein λ is a laser beam wavelength, NA is an objective lens numerical aperture, and P T is a track pitch, thereby forming a recorded mark having opposite ends extending out of the groove. This enables high density recording and increases the data transfer rate of a phase change optical recording medium.

摘要： When manufacturing a write-once recording medium which contains an oxide having a lower oxygen content as a main component, if film formation of a recording layer is performed by introducing a large amount of oxygen into the film forming gas and the sputtering target does not contain oxygen, each medium produced has different properties, because a variation of oxygen flow in the gas easily occurs and the composition ratio of oxygen which is contained in the recording layer easily varies.
To solve the problems above, an information recording medium, having at least a recording layer on a substrate and being able to record and reproduce information, contains an oxide A-O or A-O-M (A is a material which contains at least any one of Te, Sb, Ge, Sn, In, Zn, Mo and W, and M is a material which contains at least any one of a metal element, a semi-metal element, and a semiconductor-metal element), and a sputtering target used in the process of producing the layer contains at least A-O and, A and /or M. In this way, a recording layer having high reproducibility and stable properties can be produced, even in a mass production line.

摘要： A phase change optical recording medium is disclosed including at least a supporting substrate, and recording layer essentially consisting of AgInSbTe alloy compositions feasible of implementing recording and readout steps utilizing the change in reflectivity. The recording medium is characterized by the relation v 0 ≥ 0.7 v WH , where the critical relative velocity of phase change, v 0 , defined by the value of v, at which the differential coefficient, - dR (v) /dv, reaches a maximum, when the recording medium moves against an optical unit during the recording steps at a relative velocity, v, ranging from minimum and maximum relative velocities warranted for the recording medium, V WL and V WH , respectively. In addition, when the reflectivity is measured with varying erase power P E at the linear relative scanning velocity v 0 , the reflectivity of the recording layer as a function of erase power, R(P E ), preferably has a minimum. The recording layer included in the recording medium is devised to have an activation energy of deterioration of equal to, or larger than 1.6 eV, which is obtained by measuring asymmetry, A, and calculating according to the equations, k = dt/ dA, and k = k 0 x exp(E a /k B T). The recording medium is also characterized by activation energy of displacement of the boundary, ranging from 1.0 eV to 2.4 eV, which is obtained from the rate of decrease in the area, S, of the amorphous regions as recorded marks with time according to Arrhenius' equation.
