Abstract
A recording medium suitable for writing and reading out information by irradiating a photobeam onto a recording layer at a relatively low power, includes a light transmissible substrate, a light transmissible subbing layer, and a recording layer. The recording layer includes a radiation transmissible substrate, a radiation transmissible subbing layer composed of an inorganic material laminated on the substrate, and a recording layer composed of a sublimable organic substance layer laminated on the subbing layer and a metal layer laminated on the organic layer. Alternatively, the recording layer can include a radiation transmissible substrate, a radiation transmissible subbing layer composed of an inorganic material laminated on the substrate, and a recording layer the composed of a first metal layer laminated on the subbing layer, a sublimable organic substance layer laminated on the first metal layer, and a second metal layer laminated on the sublimable organic substance layer the recording medium has a high photosensitivity and can record information at a high quality (i.e., a high signal-to-noise ratio).
