Patent number: 8541086Abstract: 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.Type: GrantFiled: October 22, 2008Date of Patent: September 24, 2013Assignee: Sony CorporationInventors: Mitsuaki Oyamada, Norihiro Tanabe
