摘要： The present invention can record or reproduce information in a stable manner with a simple configuration. According to the present invention, since a photoinitiator whose vaporization temperature is between 140 and 400 deg C is included, a portion around a focal point Fb of a recording optical beam L2c heats up after the recording optical beam L2c is focused, vaporizing the photoinitiator. As a result, an air bubble is formed. This air bubble is left in a recording layer 101 as a cavity after the emission of the recording optical beam L2c ends and the portion around the focal point Fb cools down. When a reading optical beam L2d is emitted, the air bubble can reflect the reading optical beam L2d due to the difference in refractive index between a portion inside the air bubble and the portion outside the air bubble (i.e. the recording layer 101), producing a returning optical beam L3.
