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.

摘要： The present invention provides an optical information recording medium that can stably carry out the recording or reproducing of information with a simple structure. Since the optical information recording medium of this invention contains a photo-polymerization initiator with the evaporation temperature in the range of 140ºC-400 ºC, a recording light beam (L2c) is concentrated to heat a portion in the vicinity of the focus (Fb) of the recording light beam (L2c). The heat volatilizes the photo-polymerization initiator, so that it can form bubbles. The bubbles are left as cavities in the recording layer (101) after the irradiation of the recording light beam (L2c) is completed and the area in the vicinity of the focus (Fb) is cooled down. When a reading-out beam (L2d) is irradiated to the bubbles, the difference between the bubble internal refractive index and the recording layer (101) refractive index as the bubble external one reflects the reading-out beam (L2d) and makes it possible to generate a returning beam (L3).

摘要： An optical information recording medium including a recording layer that can record a large amount of information is manufactured using a simple system. A single recording layer is formed by bonding two optically transparent substrates on which the first photosensitive polymer and the second photosensitive polymer are spread such that the layers of the photosensitive polymers face each other. Furthermore, since the absorptivity of light in the recording layer increases as the focal point of light for information recording moves in a depth direction, information can be recorded without decreasing the recording transfer rate of the information.
