Abstract (en)
[origin: WO9918571A1] The invention relates to an inscribable optic storage medium comprising a protective layer, one or more inscribable layers, optionally a reflecting layer and at least one support layer. The support layer has at least one colorant with at least 70 % transmission at the laser wavelength used for writing and/or reading, and with at least 70 % absorption at all other wavelengths of visible light which are at least 100 nm shorter than the wavelength of the laser light.
