An optical information recording medium, comprising
- a recording layer in which a recording mark formed of a cavity is formed in accordance with a light for recording, and which contains therein a compound having a skeleton expressed by the general formula (1):
- where R1, R2, R3, and R4 are either hydrogen atoms or substituents.
An optical information recording medium, comprising
- a recording layer in which a recording mark formed of a cavity is formed in accordance with a light for recording, and a recording time for which a recording mark is formed at the shortest time is shortened inversely proportional to a light intensity to the M-th power (M≧2.9).
An optical information recording medium, comprising
- a recording layer in which a recording mark formed of a cavity is formed in accordance with a light for recording, and which contains therein a multiple-photon absorption material adapted to cause a multiple-photon absorption reaction as a primary constituent.
An optical information recording medium, comprising
- a recording layer in which a recording mark formed of a cavity is formed in accordance with a light for recording, and which contains therein either a polymer or a copolymer of a bisphenol-A having a skeleton expressed by the general formula (6):
