GOLD DISC vs PURPLE DISC

Why should we buy the Gold disc (original) and not the purple disc (dvd-R)

Can you see the different between DVD-R and Original DVD?

DVD-R is easily scratched and this will affect the image and sound quality. And this won't happen to Original DVD

In conclusion, Original DVD has better quality than DVD-R

  

===========================================

this is what people used to know, but in my opinion the gold disc isn't always the best . it also depends on the way you're using the disc. without a proper use both disc could get scratch.
they are also others factors like price and others

but for anti piracy. They would prefer the gold disc rather than the purple disc
