摘要： In a method of recording optical information, one of correcting ways for correcting the pulse waveform of the input signal to be recorded is selected depending on change in relative velocity between the optical information recording medium and the laser beam spot; and thereafter the laser beam output power is modulated in a range between an erasing level and a recording level in accordance with the corrected pulse waveform of the modulated input signal. Then a digital input signal corrected by modulation in pulse width is overwritten onto an optical information recording medium with a single laser beam spot by forming recording marks corresponding to the input pulse signal.

摘要： Before a signal is recorded on an optical disk, irradiations are made with plural light irradiation conditions of variable irradiation power or pulse width, optical conditions of irradiated portions are detected by detecting changes in the reflectivity or transmissivity or errors, and the optimum irradiation conditions are determined by comparing the detected results and the light irradiation conditions. In particular, by determining the optimum irradiation conditions in reference to the point where the change in reflectivity or transmissivity is greatest with respect to changes in the irradiation power, the optimum light irradiation conditions can be determined in a short time.

摘要： Disclosed is an optical information recording member which permits recording of optical information at a high speed and high density by means of energy of light or heat, as well as a high speed reproduction of the recorded information. The optical information recording member has a thin film formed on a substrate which thin film is made of TeOx constituted by a mixture of Te and TeO.sub.2 with a small amount of Au being added such that the contents of Te, O and Au in the thin film falls within a predetermined region limited in terms of atomic percent. The optical information recording member of the invention having the thin film of Te-O-Au system permits the information to be recorded in quite a short time thus allowing quite high speed of recording and reproduction as compared with the conventional recording film of TeOx system. The optical information recording member of the invention also brings about a higher recording sensitivity and a higher C/N ratio. Further, the optical information recording member may have a thermal diffusion layer of a metal having a higher heat conductivity than the thin film, formed on at least one side of the recording thin film, thereby making uniform and stabilizing the recording bits. In consequence, undesirable distortion of the recording bits is prevented even when an excessively large recording power is irradiated, thus affording a wider adaptability of the optical information recording member.

The recording medium includes a signal substrate (100), a signal recording layer (110), and a transparent cover layer (125) having a first transparent layer (115) and a second transparent layer (120), which is harder than the first transparent layer (115).

The first transparent layer is formed so as to have a first predetermined distribution of thickness. The second transparent layer is formed so as to have a second predetermined distribution of thickness to make the total thickness of the transparent cover layer (125) uniform. The first transparent layer (115) may be made of a plurality of thin laminated transparent layers.

摘要： When a separation layer is formed using a stamper between a substrate and the stamper on a thick substrate, on the surface of which a rewritable recording multilayer film provided with signal guide grooves or pits and the signal guide grooves or pits are transferred from the stamper to the surface, variations in the thickness of the separation layer are produced due to unevenness of the distance between the stamper and the substrate.The surface of the kth signal recording layer of the kth signal substrate is shaped parallel to the surface with the guide grooves and pits of the (k−1)th signal recording layer on the (k−1)th stamper, a (k−1)th separation layer is formed between the two and then the (k−1)th stamper is peeled off. The distance between the surface with the guide grooves and pits of the (k−1)th signal recording layer and the kth signal recording layer becomes uniform, and therefore the thickness of the (k−1)th separation layer can be kept uniform.
