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 had the CD stoplight and used it for a while, but have gotten away from it over the last several years. It seemed to improve the sound on some discs while doing nothing on others. I have never had it detract from the sound of a CD, but I'm not sure how you could detract from the sound of CD, it sounds bad enough already!

I never had any loss of information--it could happen, I guess, if you get sloppy and cover up any of the pits the laser is supposed to be reading. Never have had to remove any, but I'd be careful about it-as long as it doesn't adversely affect the SACDs, you might want to leave well enough alone. Perhaps there's another way--if you remember your basic colors, mix the green with blue to get yellow, then mix that with red to get orange!! (That may have been a little tongue-in-cheek).

Gunbei, you of all people are someone I thought would have used the green pen tweak. Hell, if you look at the tip under a magnifying glass, it even looks like you (or at least your almost-namesake).

I gotta watch myself, I use so many black markers everyday I might create a challenging scenario for the laser on the data side of the disc, heheh. Green guy using black markers? Hmmm...

ok...i tried them both...the green audioprism cd stoplight pen...it worked...and no...i had no problems...i was always able to color between the lines so i didn't get any where the laser was supposed to go.

the black "sharpie" pens...you know...the indelible laundry markers...well...that one didn't do jack for me.

I agree with Rcprince. No loss of info that I have heard. Sometimes it works and sometimes it doesn't make any improvement, I think the edges have something to do with it, some are smooth and some are not.

Try it for yourself.

Happy Listening
