摘要：
An optical data storage medium includes a substrate, an optical data storage layer overlaid on the substrate and a reversible image recording layer overlaid on the optical data storage layer, in which information is recorded in the reversible image recording layer so as to be visible. The reversible image recording layer, which includes a matrix resin and a low-molecular-weight organic substance dispersed in the matrix resin, may preferably be thermosensitive and change its transparency or color tone in response to heat.
