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： 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： An optical information recording medium having two or more information layers, wherein the irradiation of either the information layer with a laser beam converging thereon causes information signals to be recorded or reproduced; the nearer positioned information layer than the farthest information layer as viewed from the incidence side of the laser beam has a recording layer varying between two optically detectable states, and 0≦|Tc−Ta|/Tc≦0.1 where Tc is the transmittance of the nearer positioned information layer when the recording layer is in state (a) and Ta, the transmittance, when it is in state (b). This makes possible accurate accurately recording and reproduction of information onto and out of the farther information layer irrespective of whether or not any information is recorded on the nearer information layer.

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.
摘要翻译：磁盘上的轨道在其径向位置被分成多个同心区域。在记录期间，角速度根据被记录的区域而变化，并且以旋转速度驱动盘，其中角速度在任何单个区域内是恒定的，但随着被访问的轨道的区域的径向位置接近外部而减小盘的周长。在再现期间，以旋转速度驱动盘，其中角速度在所有区域中是恒定的。因此，磁头与磁道的相对线速度的变化范围变小，记录时记录条件的变化较小。在再现期间，不需要用于盘的旋转控制的延迟时间，并且可以更快速地访问期望的轨道。
