摘要：
This invention relates to a recording medium in which a transition metal oxide showing photochromism is used as the recording layer and the said recording layer or an upper layer adjacent to the recording layer is made to carry a proton donor. This recording medium makes it possible to improve the change efficiency of optical density change produced by optical writing.
