RECORDABLE OPTICAL RECORD CARRIER FOR MULTILEVEL AND METHOD FOR WRITING THEREON

摘要

A recordable optical record carrier is provided comprising a recording dye layer, whereby said recording dye layer (111) comprises at least two organic dye materials being absorptive at different wavelengths. Further, a method f or writing on such a recordable optical record carrier is proposed. According t o the method marks representing the data are written via a writing laser beam at a first predetermined wavelength according to a writing strategy providing a channel bit length and a mark width appropriate for read-out by a beam of electromagnetic radiation at a second predetermined wavelength being differe nt from said first predetermined wavelength.
