    摘要: An erasable optical information recording medium has a transparent substrate, and a recording layer supported by the substrate. The recording layer includes a thin film of at least one polydiacetylene having side chains. The polydiacetylene is capable of undergoing a reversible planar-nonplanar transition of the main chain structure of the polydiacetylene due to a conformational change of the side chains produced by irradiation of light. When the recording layer is irradiated with light, the reversible planar-nonplanar transition occurs at the irradiated portions to cause a corresponding change of optical properties of the recording layer, thereby recording information thereinto and erasing information therefrom.
