<p>A multi-color, high density recording medium including a substrate having at least two patterned interference filters formed thereon is described. Each of the filters transmits a different wavelength range of visible light and each of the filters comprises an unpatterned interference layer of an inorganic material which is substantially absorption-free in the visible wavelength range of the spectrum. At least one of the interference filters formed on the substrate comprises a first, unpatterned reflecting layer positioned on one side of the respective interference layer, and a second, patterned reflecting layer positioned on the other side of the respective interference layer, such that the pattern of only the first reflecting layer forms the pattern of the at least one interference filter.</p> |
