Markering of CD Edges


Has anyone who "paints" the edges of their CDs with various-colored markers noticed any loss of information after marking their discs? There's a thread over at Audio Asylum, where one person indicates that marking up the edges of a disc actually decreases readability and increases errors. I personally haven't noticed this effect--actually, quite the opposite--but I'm wondering what others' experiences are.

In addition, does painting the edge of an SACD green have any deleterious effect? I just found out that green is not the appropriate color to use on SACDs, but that information comes after marking up about 50 SACDs. Can I just leave the green markering on, or is it having a negative effect and should I remove it with rubbing alcohol?

Many thanks for any responses.

How the hell do you do that Marco? I couldn't even get close to 178 Fred's on my discs. By the time I circumnavigated that silver flat world I only had 33 little Fred's drawn. And I'm an artist!
Dean - you need the Pass Labs Fred's Head Signature magnifying loupe and specially modified Fred's Head green and blue razor-point Sharpie™ set. During the month of July it comes with a free wrist-brace from Ace Bandage and a small bottle of Gojo in the fresh orange scent. All of this for the bargain price of $379.95 (financing available). And if you act right now (1-800-FREDHED), and mention my name they'll send you Fred's likeness on the inside of a matchbook cover so you can have a guide to make sure you're accurate. I cannot stress the importance of accuracy in rendering Fred here, and this is probably what castrated Limp Bizkit for Howard. He's probably drawing expressionistic Fred's with one eye bigger than the other. Oh, and the dude with the one Dino's in for a big dissappointment too. Just Fred!

I've found that green markers work best on SACD and blue on DVD. However, red is best on "redbook" which makes sense to me. I've tried all of your picture recommendations and can't hear the difference. Should I look into a new transport? Thanks in advance to all.
With the Joe Rockhead .00000000000000007 micron green audio rapidiograph I can probably hide all kinds of nasty little drawings on my discs ala Disney.
