IIRC Sony was interested in these dubious ways to scam customers into thinking they had PREMIUM products.Some idiot in the R&D department also tried making a PREMIUM portable media player walkman... WTH?!?
Cell phones have completely taken over that space.. sony should be trying to get into the smart connected TV side of things.. there is plenty of enthusiasm into plug-in mini computers for your HD & UHD smart tv sets.
All this technology does is improve a disc data technology and dubious at that.. we need higher quality BLU RAY discs instead.. Those 4 layer BDXLs need a dirt cheap production process so they can be mass produced and get into the hands of mainstream consumers and without all the crazy royalty fees to BLU ray consortium.. which make the OEM printer companies look like saints.
