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.

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.
Sorry I didn't see this sooner.The magic marker works wonders. Remove the cap, breathe deep and you'll wonder what you've been listening to.Alcohol administered internally has a similar if more pleasant effect.
