OPTICAL INFORMATION RECORDING MEDIUM AND INFORMATION RECORDING METHOD

摘要

There is provided an optical information recording medium including, on a substrate, a recording layer in which information can be recorded by irradiating a laser beam having a wavelength of 440 nm or less, wherein the recording layer includes an oxonol dye that has a maximum absorption wavelength longer than the wavelength of the laser beam. There is also provided an information recording method including irradiating a laser beam having a wavelength of 440 nm or less to the optical information recording medium to record information.
