Abstract: PURPOSE:To enable a ternary recording, by a method wherein; an optical recording medium having a recording layer is irradiated with two lights of different exposures controlled according to recording information to change the color at an exposed portion and have a pit at the other exposed portion. CONSTITUTION:On a substrate 1, a recording layer 2 made of a layer 2a containing a diacetylene derivative (DA) compound and a layer 26 containing a squarylium dye is provided. The DA compound is polymerized and changed to a polydiacetylene derivative compound due to the irradiation of ultraviolet light to the recording layer 2. On the other hand, recording information through a control circuit is converted to optical signals by a semiconductor laser to be imaged in position on an optical recording medium. The exposure in imaging points 3a, 3b is so controlled respectively as to be limited to an exposure Q1 heating the polydiacetylene derivative compound for color changing recording up to the melting point of the recording layer 2 and an exposure Q2 heating the recording layer 2 to at least the melting point. Therefore, the imaging point 3a subjected to the exposure Q1 is changed into red to become a dot 5a ; the imaging point 3b subjected to the exposure Q2 is melted to have a pit made of a recessed portion 5b. In this manner, a ternary recording with dots of different forms is conducted on the recording layer 2 according to an input information.
