Abstract

An optical recording medium is disclosed, which comprises a substrate having thereon a recording layer which is capable of forming regions having an increased reflectivity by spinodal decomposition of the recording layer upon application thereto of energy of a threshold value or higher. Writing of information is achieved by irradiating the recording layer with no phase separation caused by spinodal decomposition with an energy beam having an intensity causing spinodal decomposition-induced phase separation in accordance with the information to be written. Reading of the information, on the other hand, is achieved by irradiating the recording layer with phase separation caused by spinodal decomposition with an energy beam having an intensity causing no spinodal decomposition-induced phase separation. The medium and the recording system using the same exhibit high sensitivity, high reflectivity, and high contract and conform to the CD or LD standard.
