摘要： A rewritable information recording medium which has a recording layer containing a Group I transition element and a Group IV representative elements of the Periodic Table as two principal element and a support substrate for physically supporting the recording layer, and an information-write, -read, and erase method using this recording medium. When the recording layer is immediately cooled after it is heated up to near a eutectic temperature of the two principal elements, two metastable phases having different energy levels appear. A state in the first metastable phase of the higher energy level has a reflectivity sufficiently higher than that of a state of a mixed phase including the second metastable phase of the lower energy level, or that of the equilibrium state. The state in the first metastable phase can be obtained by heating a recording layer in another state by light beam irradiation. A portion in the first metastable state is cooled after it is heated to a temperature lower than that for obtaining the first metastable phase, so that it can be converted to a state of the low reflectivity, i.e., a state of a mixed phase including the second metastable phase or to the equilibrium state.

The lens unit includes a metamaterial lens or a plasmon lens. The metamaterial lens has a first dielectric member in which first microstructures are implanted in a substantially regular manner. The plasmon lens has an aperture. The aperture is a hole or a slit created in a metal film. The microscopic drive unit is configured to adjust a relative position between the lens unit and the recording medium. In addition, the principal plane is placed to be in contact with the lens unit or to have a gap between the principal plane and the lens unit. Furthermore, the second microstructures are arranged periodically in a direction substantially perpendicular to the principal plane of the recording medium.

摘要： A magneto-optical recording medium including a recording layer and a bias layer being stacked one upon the other to apply coupling interaction which is mainly magnetostatic interaction to each other, the bias layer having a magnetization-reversing temperature higher than that of the recording layer. The medium is irradiated with laser beam pulses having a recording level and an erasing level lower than the recording level, thereby recording and erasing the information. When the medium is irradiated with the laser beam pulse having the recording level and the irradiated region is cooled to the magnetization reversing temperature T.sub.rR, the magnetization of the beam-irradiated region of the recording layer is aligned with a direction of the leakage magnetic field leaking from the recording layer. When the medium is irradiated with the laser beam pulse having the erase level and the irradiated region is cooled to T.sub.rR, direction of magnetization of the beam-irradiated region of the recording layer is aligned with a direction of the leakage magnetic field applied from the bias layer to the recording layer.
