The colored data storage media comprises a substrate comprising colorant and
plastic, wherein the substrate has a transmissivity of about 85% or less, at a
readback laser wavelength, when traversing a 1.2 mm thick colored substrate (disk).
Alternatively, the storage media comprises: a substrate comprising a fluorescent
colorant and plastic, wherein the substrate has a fluorescent color emission wavelength
which is not equal to the readback laser wavelength.
