Replicated CDs have actual holes in the reflective medium, while CDRs have the reflectivity of the chemical layer changed by the laser - thus the reflectivity can change with time and temp and such. Sort of like the difference between oil painting and watercolor, in a vague way... or pinholes in aluminum versus sharpie dots on foil? Sorta like that...
