摘要： An optical information recording medium of the present invention includes at least m (m is an integer of 2 or more) information layers, and each of the information layers includes a recording layer that changes irreversibly between a state A and a state B that are optically different from each other. In the case where the m information layers are taken as the first through m-th information layers in the order from a laser beam incidence side, when a recording layer included in the j-th information layer (j is an integer satisfying 1≦j≦m−1) is taken as the j-th recording layer, and when a transmittance of the j-th information layer at the time when the j-th recording layer is in the state A is TAj (%) and a transmittance of the j-th information layer at the time when the j-th recording layer is in the state B is TBj (%), the following relationship is satisfied in the j-th information layer: 0≦|TAj−TBj|/(TAj,TBj)max≦0.10 where (TAj,TBj)max is a larger value of TAj and TBj. Furthermore, at least one recording layer of the first through (m−1)th recording layers is formed of a material having a complex index of refraction (n−ik, where n is a refractive index and k is an extinction coefficient) that is different from that of the m-th recording layer.

摘要： A method for performing a high quality recording of information signals on an optical disk utilizes reversible structural changes between crystalline and amorphous states of a chalcogenide glass film or the like and two circular or nearly circular laser spots closely arranged along a recording track of optical disk. The preceding spot, which emits a continuous mode or high-frequency mode by far exceeding the recording frequency, operates cancel the past history in the irradiated portion by melting the recording film. The succeeding spot, which is modulated between the power levels for amorphizing and crystallizing according to the recorded information, operates to record new information signals on the track just after erased by the preceding laser spot.

摘要： A track on the disk is divided into plural concentric zones on the radial position thereof. During recording, the angular velocity varies according to the zones accessed for recording, and the disk is driven at a rotational velocity whereby the angular velocity is constant within any single zone but decreases as the radial position of the zone of the accessed track approaches the outside circumference of the disk. During reproducing, the disk is driven at a rotational velocity whereby the angular velocity is constant in all zones. The range of change in the relative linear velocity of the head to the track is thus smaller and the change in the recording conditions is less during recording. During reproducing, there is no delay time required for rotational control of the disk, and the desired track can be more quickly accessed.

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.
