  >"It is interesting to note that laser light from the player, drive or recorder does not travel through the BD substrate to access information on the disc. Thus it may be possible to employ materials other than the optical-grade polycarbonate plastic as used in CD, DVD and other disc construction. Indeed, polycarbonate is currently employed, but manufacturers have demonstrated that various resins (polyphenylene oxide/PPO and others) and even paper may be possibilities for the future." PDS: Interesting indeed!
