摘要： There is disclosed an optical information recording apparatus for recording optical information in a phase change type optical recording medium and a method therefor. The order of the atomic arrangement of the optical recording medium is capable of changing between a first state of order thereof and a second state of order thereof higher than the first state. A first light source generates a first light including the optical information and projecting the generated first light on the optical recording medium so as to change the order of the atomic arrangement of the optical recording medium from the first state to the second state and from the second state to the first state, mainly by heating the optical recording medium. A second light source generates a second light and projects the generated second light on the optical recording medium together with the first light so as to accelerate the change in the order of the atomic arrangement of the optical recording medium from the first state to the second state caused by the first light source by mainly exciting electrons in the optical recording medium, thereby recording the optical information in the optical recording medium.

摘要： In a method and an apparatus initializing an optical recording medium by irradiating a flash light. Walls are formed on a holder for holding the optical recording medium so as to adjoin an inner edge and an outer edge of the optical recording medium. When a flash light irradiates, a part of incident light which obliquely enters into an inner and an outer periphery regions of the optical recording medium is shaded by the walls. A quantity of the incident light incident on a unit area in each of the inner and outer periphery regions is less than that in a recording region between the inner and outer periphery regions. When temperature in the recording region reaches to an initializing temperature, the temperature in each of the inner and outer periphery regions is lower than the initializing temperature. So that neither cracks nor corrugations occur in a recording layer in the inner and outer regions.

摘要： In an optical information recording medium such that a recording layer undergoing an optically detectable phase change by absorbing a laser beam is formed on a transparent substrate having geometrically concavo-convex groove tracks concentrically or spirally formed on its surface, the shapes of the groove tracks are variably determined continuously or stepwise depending on the material of the substrate, the structure of the recording layer, and the radial locations of the tracks so that the thermal diffusivity of heat generated in the recording layer becomes larger in an inner part than in an outer part whereby the differences of recording characteristics between in an inner part and in an outer part are suppressed, and the effective recording area is enlarged. There is also disclosed an optical information recording medium having outer zone in which the groove width decreases monotonically or stepwise as recording radius decreases and inner zone in which the land width increases monotonically or stepwise as recording radius increases.

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.
