i'm going to guess it's those cassettes they used to have that only had 1 or 2 songs on them and they cost like $5 or something.

I've seen magic marker melt the CD-R, but that was about 6 years ago. I've never had a problem with a Sharpie.

I've seen magic marker melt thru the paint on a car, too.

anyone who uses one of those on a CDR is just asking for trouble.

I've heard from an anal source that the light from the laser can pass through this region and cause havoc. He colored in that area to stop the light from passing though - something about it bouncing round within the housing of the burner and causing errors during the burn...

I can tell you from personal experience that non water based markers will eventually bleed through the plastic laminate and destroy the aluminum layer where the data is written. It has happened to a few of my CDs over the years. To avoid this from happening, either use water based markers or write over an area that is not over the data on the other side (such as the inner hub or outer edge).

A software engineer/computer geek coworker always poked fun at me for believing this "myth"...until it happened to him. He even showed me the CD that went bad. When he held it up to the lights, you could actually see right through where he had written with a Sharpie!

These days, I use LightScribe for disks that I will be keeping for a long time. Sharpie works fine for all others.

Why would the laser be pointing at a part of the disc it can't right on? One of the nifty things about laser light is that it goes exactly where you point it in a beam that doesn't get any bigger as it travels away from the source. That's why they employ lasers instead of light bulbs to write and read CD's.

But we all think outlining the edge in green Sharpie is mandatory for warm tone, right?

I think that you must've missed the post that Rynders was responding to.

I've got cd-r discs that were written on with sharpies years ago that still playback fine and look fine. I still buy the water-based ink pens, though, just to be safe.

OOOPS! I thought he was responding to the post about only writing on the hub. Never mind.
