I still paint the edge of ALL CDs. DVDs with a black ring. Using a normal. cheap permanent marker pen. I long ago used a UniPosca green paint pen, But when I ran out of those I started to use the black marker. Just as good.
Does it help with better sound? Most times. Not always. pretty subtle.
The laser light bouncing around off the edge? yeah, it reduces the scatter.
I also rub the surfaces with old (ancient really) Audio Quest juice from small $0.25 packets. I bought a box of 100. And take a packet, dump it into a small square of cotton cloth. Then I use that.. one lasts a year, easy. I wasted a lot of the packets early.. on CD cases.. Still have about 15 packets left. 15 years worth...
.
The main, and MOST IMPORTANT thing I do is use a cosmetic blush brush and brush off the back and front of every single CD SACD DVD I place in a player.Always, every time.Taking off the tiny dust which is what actually kills lasers. The lens.. The laser reads so close to the surface, it is like an invisible to the eye smoke particle or skin dander is a boulder to the lens.. BLAM BAM WHACK. constantly if you DO NOT clean the disc every time.
