Red and green double-wavelength storage CD for single kind organic dye film

This invention relates to a storage CD of red and green dual wavelength of a signel organic dye. A registered layer covered the base plate is made of indole tribasic with the thickness of 64-98 nm inthe disk and a reflection layer covered on the registered layer is made of AL film of 50-60 nm. Th head and end of the absorption band of the dye layer making up of above registered layer are at two specific laser wavelengths of red and green with the same absorbability and matched multi-film structure with high enough reflectivity and reflectivity contrast at the red and green laser wavelengths.So this invention enables use to make one time registration to read out with red and green dual wavelengths at the single organic dye registration layer.
