Optical information recording medium
摘要:
The present invention provides an optical information recording medium comprising a substrate including a groove that has a track pitch of 200 to 400 nm and a depth of 20 to 150 nm, the substrate having successively disposed thereon a light-reflective layer, a recording layer containing a dye and on which information is recordable by a laser beam having a wavelength of 600 nm or less, and a cover layer, wherein the recording layer contains at least two organic solvent-soluble compounds each having an absorption maximum in the range of 300 to 450 nm and a specific absorbance at a recording laser wavelength.
