Abstract:
A dye or dyes are selected, which are capable of absorbing a laser beam with a wavelength of 350 to 500 nm and are capable of recording sub-information using a laser beam with a wavelength of 640 to 680 nm or 750 to 830 nm. An optical information recording medium including the optical recording layer records sub-information (BCA information) of a type different from that of main information (data information) in a sub-information region (a BCA recording region) different from a main information area (a data area) using a laser beam.
