摘要:
A first write-once type recording layer, on which information can be recorded by being irradiated with a laser beam having a wavelength of not more than 450 nm, is provided on a first substrate of a first optical information-recording medium. A dye compound, which contains boron as a constitutive element, is contained in the first write-once type recording layer. Preferred examples of the dye compound include boronic acid. In particular, it is preferable to use a compound having a boroxin moiety formed by condensation of boronic acid. The condensation of boronic acid can be advanced such that a solution, which is prepared by dissolving boronic acid in a solvent, is applied onto the first substrate to form the first write-once type recording layer, and then the first write-once type recording layer is subjected to an annealing treatment.
